btrfs: remove btrfs_folio_end_all_writers()
The function btrfs_folio_end_all_writers() is only utilized in
extent_writepage() as a way to unlock all subpage range (for both
successful submission and error handling).
Meanwhile we have a similar function, btrfs_folio_end_writer_lock().
The difference is, btrfs_folio_end_writer_lock() expects a range that is
a subset of the already locked range.
This limit on btrfs_folio_end_writer_lock() is a little overkilled,
preventing it from being utilized for error paths.
So here we enhance btrfs_folio_end_writer_lock() to accept a superset of
the locked range, and only end the locked subset.
This means we can replace btrfs_folio_end_all_writers() with
btrfs_folio_end_writer_lock() instead.
