[PATCH 16/17] btrfs: use btrfs_finish_ordered_extent to complete direct writes

[Christoph Hellwig <hch@lst.de>]

Use the btrfs_finish_ordered_extent helper to complete compressed writes
using the bbio->ordered pointer instead of requiring an rbtree lookup
in the otherwise equivalent btrfs_mark_ordered_io_finished called from
btrfs_writepage_endio_finish_ordered.
