Btrfs fixes for 7.2-rc7, part 1

Hi,

the following branch contains a few short fixes. This is separate from the 'fixup worker' pull request, just in case.

Please pull, thanks.

- fix leak in encoded ioctl write

- disable large folios on systems with highmem

- disable block size > page size when there's no transparent hugepage support (under experimental config)

- reject compressed inline extents without valid LZO headers

- properly initialize cached inode mapping (if block size > page size)
