[GIT PULL] Btrfs fixes for 6.14-rc5

[David Sterba]

Hi,

please pull a few more fixes. Thanks.

- extent map shrinker fixes
  - fix potential use after free accessing an inode to reach fs_info,
    the shrinker could do iput() in the meantime
  - skip unnecessary scanning of inodes without extent maps
  - do direct iput(), no need for indirection via workqueue

- in block < page mode, fix race when extending i_size in buffered mode

- fix minor memory leak in selftests

- print descriptive error message when seeding device is not found
