[GIT PULL] Btrfs fixes for 6.18-rc2

[David Sterba <dsterba@suse.com>]

Hi,

please pull a bunch of one-liners and short fixes. Thanks.

- in tree-checker fix extref bounds check

- reorder send context structure to avoid -Wflex-array-member-not-at-end
  warning

- fix extent readahead length for compressed extents

- fix memory leaks on error paths (qgroup assign ioctl, zone loading
  with raid stripe tree enabled)

- fix how device specific mount options are applied, in particular the
  'ssd' option will be set unexpectedly

- fix tracking of relocation state when tasks are running and
  cancellation is attempted

- adjust assertion condition for folios allocated for scrub

- remove incorrect assertion checking for block group when populating
  free space tree
