[GIT PULL] Btrfs fixes for 6.8-rc6

[David Sterba]

Hi,

two more fixes. Please pull, thanks.

- fix a deadlock in fiemap, there was a big lock around the whole operation
  that can interfere with a page fault and mkwrite, reducing the lock
  scope can also speed up fiemap

- fix range condition for extent defragmentation which could lead to worse
  layout in some cases
