[GIT PULL] Btrfs fixes for 5.16-rc5

[David Sterba <dsterba@suse.com>]

Hi,

a few more regression fixes and stable patches, mostly one-liners.
Please pull, thanks.

Regression fixes:

- fix pointer/ERR_PTR mismatch returned from memdup_user

- reset dedicated zoned mode relocation block group to avoid using it
  and filling it without any recourse

Fixes:

- handle a case to FITRIM range (also to make fstests/generic/260 work)

- fix warning when extent buffer state and pages get out of sync after
  an IO error

- fix transaction abort when syncing due to missing mapping error set on
  metadata inode after inlining a compressed file

- fix transaction abort due to tree-log and zoned mode interacting in an
  unexpected way

- fix memory leak of additional extent data when qgroup reservation
  fails

- do proper handling of slot search call when deleting root refs
