b29e197aaf bcachefs: Invalidate buckets when writing to alloc btree
Prep work for persistent alloc information. Refactoring also lets us
make free_inc much smaller, which means a lot fewer buckets stranded on
freelists.

c692399529 bcachefs: don't call bch2_bucket_seq_cleanup from journal_buf_switch
journal_buf_switch is called from the foreground when getting a journal
reservation and thus is somewhat latency sensitive;
bch2_bucket_seq_cleanup has to run infrequently but is a bit expensive
when it does run.

Call it from the journal write path instead, and punt the journal write
to worqueue context.

88c07f7397 bcachefs: Only check inode i_nlink during full fsck
Now that all filesystem operatinos that manipulate the filesystem
heirachy and i_nlink are fully atomic, we can add a feature bit to
indicate i_nlink doesn't need to be checked.
