The extent_io_tree::private_data was meant to be a preparatory work for
the metadata inode rework but that never materialized. Now it's used
only for an inode so it's better to change the appropriate type and
rename it.

After previous patches the unused parameters can be removed from

There's a callback function parameter for btrfs_wq_submit_bio that can
be one of: metadata, buffered data, direct io data. The callback
abstraction is unnecessary as we have all functions available.
Replace the parameter with a command that leads to a direct call in
run_one_async_start. The called functions can be then simplified and we
can also remove the extent_submit_bio_start_t typedef.

There's a function pointer passed to btrfs_repair_one_sector that will
submit the right bio for repair. However there are only two callbacks,
for buffered and for direct IO. This can be simplified to a bool-based
switch and call either function, indirect calls in this case is an
unnecessary abstraction. This allows to remove the submit_bio_hook_t
typedef.

Currently we have inline extent read code behind two levels of
indentation, factor them them out into a new function,
read_inline_extent(), to make it a little easier to read.
Since we're here, also remove @extent_offset and @pg_offset arguments
from uncompress_inline() function, as it's not possible to have inline
extents at non-inline file offset.

The argument @new_inline changes the following members of extent_map:
- em->compress_type
- EXTENT_FLAG_COMPRESSED of em->flags
However neither members makes a difference for inline extents:
- Inline extent read never use above em members
As inside btrfs_get_extent() we directly use the file extent item to
do the read.
- Inline extents are never to be split
Thus code really needs em->compress_type or that flag will never be
executed on inlined extents.
(btrfs_drop_extent_cache() would be one example)
- Fiemap no longer relies on extent maps
Recent fiemap optimization makes fiemap to search subvolume tree
directly, without using any extent map at all.
Thus those members make no difference for inline extents any more.
Furthermore such exception without much explanation is really a source
of confusion.
Thus this patch will completely remove the argument, and always set the
involved members, unifying the behavior.

Currently for inline extents read inside btrfs_get_extent(), we will
reset several extent map members:
- em->start
Reset to extent_start, which is completely unnecessary.
The extent_start and em->start should have already be zero, ensured by
tree-checker already.
- em->len
Reset the round_up(copy_size, fs_info->sectorsize), which is again
unnecessary.
- em->orig_block_len
Reset to em->len (sectorsize), while it is originally unset from
btrfs_extent_item_to_extent_map().
This makes no difference, as all extent map handling paths will
ignore the orig_block_len if they found it's an inlined extent.
Such inline extent orig_block_len ignoring examples can be found in
btrfs_drop_extent_cache().
- em->orig_start
Reset to em->start (0), while it is originally set to EXTENT_MAP_HOLE.
This makes no difference either, as all extent map handling paths will
ignore the em->orig_start if they found it's an inline extent.
Thus all these em members resetting are unnecessary.
Replace them with ASSERT()s checking the only two members (block_start
and length) that make sense.

Currently we calculate inline extent read in a way that inline extent
can start at non-zero offset.
This is consistent with the inode selftests, which puts an inline extent
at file offset 5.
Meanwhile the inline extent creation code will only create inline extent
at file offset 0.
Furthermore with the introduction of tree-checker on file extents, we are
actively rejecting inline extent which starts at non-zero file offset.
And so far we haven't yet seen any report of rejected inline extents at
non-zero file offset.
This all means, the extra calculation to support inline extents at
non-zero file offset is mostly paper weight, and damaging the
readability of the code.
Thus this patch will:
- Add extra ASSERT()s to make sure involved file offset are all 0
- Remove @extent_offset calculation
- Simplify the involved code
As several variables are now single-use, no need to declare them as
a variable anymore.
