Btrfs fixes for 7.2-rc5

Hi,

please pull the following fixes. I'm catching up with fix backlog in the development branch, so here's a number of them and will probably send one more for this or the next rc.

Thanks.

- relocation fixes
- skip attempting compression on reloc inodes
- exclude inline extents from file extent offset checks
- fix minor memory leak after error when adding reloc root
- fix root cleanup after inserting and merging

- fix clearing folio tags after writeback

- clear logging flag of extent map before splitting

- fix unsigned 32/64 type conversions when accounting dirty metadata, leading to continually exceeding threshold

- fix regression in 32bit compat ioctl for subvolume info

- fix type of SEARCH_TREE ioctl buffer in UAPI header

- fix expression in ASSERT expression which can be unconditionally evaluated on some compilers

- only account delalloc bytes for regular inodes
