[GIT PULL] Btrfs fixes 6.4-rc7, part 2

[David Sterba]

Hi,

here's the second part, two fixes for NOCOW files, a regression fix in
scrub and an assertion fix. Please pull, thanks.

- NOCOW fixes:
  - keep length of iomap direct io request in case of a failure
  - properly pass mode of extent reference checking, this can break
    some cases for swapfile

- fix error value confusion when scrubbing a stripe

- convert assertion to a proper error handling when loading global
  roots, reported by syzbot
