[GIT PULL] Btrfs fixes for 6.0-rc7

[David Sterba]

Hi,

a few more fixes, also for stable backports. Please pull, thanks.

- two fixes for hangs in the umount sequence where threads depend on
  each other and the work must be finished in the right order

- in zoned mode, wait for flushing all block group metadata IO before
  finishing the zone
