From: Qu Wenruo <wqu@xxxxxxxx> commit 34b127aecd4fe8e6a3903e10f204a7b7ffddca22 upstream. The last user of btrfs_bio::flags was removed in commit 326e1dbb5736 ("block: remove management of bi_remaining when restoring original bi_end_io"), remove it. (Tagged for stable as the structure is heavily used and space savings are desirable.)
