[GIT PULL] Btrfs fixes for 5.18-rc3

[David Sterba]

Hi,

a few more code fixes and a warning fixes. There's one feature ioctl
removal patch slated for 5.18 that did not make it to the main pull
request.  It's just a one-liner and the ioctl has a v2 that's in use for
a long time, no point to postpone it to 5.19.

Please pull, thanks.

- fixes:
  - add back cgroup attribution for compressed writes
  - add super block write start/end annotations to asynchronous balance
  - fix root reference count on an error handling path
  - in zoned mode, activate zone at the chunk allocation time to avoid
    ENOSPC due to timing issues
  - fix delayed allocation accounting for direct IO

- remove balance v1 ioctl, superseded by v2 in 2012

- warning fixes:
  - simplify assertion condition in zoned check
  - remove an unused variable
