[GIT PULL] Btrfs fixes for 6.4-rc7

[David Sterba <dsterba@suse.com>]

Hi,

a few more fixes and regression fixes. This pull request got a bit
delayed due to testing and there are at least two more fixes I'd like to
get merged to 6.4-rc7, expected to be sent in time.

Please pull, thanks.

- in subpage mode, fix crash when repairing metadata at the and of a
  stripe

- properly enable async discard when remounting from read-only to
  read-write

- scrub regression fixes:
  - respect read-only scrub when attempting to do a repair
  - fix reporting of found errors, the stats don't get properly
    accounted after a stripe repair
