btrfs: make find_first_extent_bit() return a boolean

Currently find_first_extent_bit() returns a 0 if it found a range in the
given io tree and 1 if it didn't find any. There's no need to return any
errors, so make the return value a boolean and invert the logic to make
more sense: return true if it found a range and false if it didn't find
any range.

btrfs: check for commit error at btrfs_attach_transaction_barrier()

btrfs_attach_transaction_barrier() is used to get a handle pointing to the
current running transaction if the transaction has not started its commit
yet (its state is < TRANS_STATE_COMMIT_START). If the transaction commit
has started, then we wait for the transaction to commit and finish before
returning - however we completely ignore if the transaction was aborted
due to some error during its commit, we simply return ERR_PT(-ENOENT),
which makes the caller assume everything is fine and no errors happened.

This could make an fsync return success (0) to user space when in fact we
had a transaction abort and the target inode changes were therefore not
persisted.

Fix this by checking for the return value from btrfs_wait_for_commit(),
and if it returned an error, return it back to the caller.

Merge tag 'for-6.5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"Mainly core changes, refactoring and optimizations.

Performance is improved in some areas, overall there may be a
cumulative improvement due to refactoring that removed lookups in the
IO path or simplified IO submission tracking.

Core:

- submit IO synchronously for fast checksums (crc32c and xxhash),
remove high priority worker kthread

- read extent buffer in one go, simplify IO tracking, bio submission
and locking

- remove additional tracking of redirtied extent buffers, originally
added for zoned mode but actually not needed

- track ordered extent pointer in bio to avoid rbtree lookups during
IO

- scrub, use recovered data stripes as cache to avoid unnecessary
read

- in zoned mode, optimize logical to physical mappings of extents

- remove PageError handling, not set by VFS nor writeback

- cleanups, refactoring, better structure packing

- lots of error handling improvements

- more assertions, lockdep annotations

- print assertion failure with the exact line where it happens

- tracepoint updates

- more debugging prints

Performance:

- speedup in fsync(), better tracking of inode logged status can
avoid transaction commit

- IO path structures track logical offsets in data structures and
does not need to look it up

User visible changes:

- don't commit transaction for every created subvolume, this can
reduce time when many subvolumes are created in a batch

- print affected files when relocation fails

- trigger orphan file cleanup during START_SYNC ioctl

Notable fixes:

- fix crash when disabling quota and relocation

- fix crashes when removing roots from drity list

- fix transacion abort during relocation when converting from newer
profiles not covered by fallback

- in zoned mode, stop reclaiming block groups if filesystem becomes
read-only

- fix rare race condition in tree mod log rewind that can miss some
btree node slots

- with enabled fsverity, drop up-to-date page bit in case the
verification fails"
