Subject: btrfs: Remove btrfs_bio::flags member
Git-commit: 34b127aecd4fe8e6a3903e10f204a7b7ffddca22
Patch-mainline: 5.5-rc1
References: bnc#1151927 5.3.17

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.)
