[GIT PULL] Btrfs fixes for 7.1-rc2

[David Sterba <dsterba@suse.com>]

Hi,

please pull the following batch of fixes that arrived shortly before or
during the merge window.

Thanks.

- space reservation fixes
  - correctly undo 'may_use' accounting for remap tree
  - avoid double decrement of 'may_use' when submitting async io

- actually enable the shutdown ioctl callback (not just the superblock ops)

- raid stripe tree fixes when deleting extents
  - add missing error handling
  - fix various incorrect values set

- fix transaction state when removing a directory, possibly leading to
  EIO during log replay

- additional b-tree node key checks during metadata readahead

- error handling and transaction abort updates
