[GIT PULL] Btrfs fixes for 6.15-rc6

[David Sterba <dsterba@suse.com>]

Hi,

a few more fixes, minor updates and one revert. Please pull, thanks.

- revert device path canonicalization, this does not work as intended
  with namespaces and is not reliable in all setups

- fix crash in scrub when checksum tree is not valid, e.g. when mounted
  with rescue=ignoredatacsums

- fix crash when tracepoint btrfs_prelim_ref_insert is enabled

- other minor fixups
  - open code folio_index(), meant to be used in MM code
  - use matching type for sizeof in compression allocation
