Btrfs fixes for 7.1-rc2

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
