btrfs: fix silent IO error loss in encoded writes and zoned split

btrfs: fix silent IO error loss in encoded writes and zoned split

can_finish_ordered_extent() and btrfs_finish_ordered_zoned() set
BTRFS_ORDERED_IOERR via bare set_bit(). Later,
btrfs_mark_ordered_extent_error() in btrfs_finish_one_ordered() uses
test_and_set_bit(), finds it already set, and skips
mapping_set_error(). The error is never recorded on the inode's
address_space, making it invisible to fsync. For encoded writes this
causes btrfs receive to silently produce files with zero-filled holes.

Fix: replace bare set_bit(BTRFS_ORDERED_IOERR) with
btrfs_mark_ordered_extent_error() which pairs test_and_set_bit() with
mapping_set_error(), guaranteeing the error is recorded exactly once.
