David Sterba ccaa66c8dd Revert "btrfs: compression: drop kmap/kunmap from lzo" 
This reverts commit 8c945d32e60427cbc0859cf7045bbe6196bb03d8.

The kmaps in compression code are still needed and cause crashes on
32bit machines (ARM, x86). Reproducible eg. by running fstest btrfs/004
with enabled LZO or ZSTD compression.

The revert does not apply cleanly due to changes in a6e66e6f8c1b
("btrfs: rework lzo_decompress_bio() to make it subpage compatible")
that reworked the page iteration so the revert is done to be equivalent
to the original code.
