[GIT PULL] Btrfs fix for 5.13-rc7

[David Sterba <dsterba@suse.com>]

Hi,

one more fix, for a space accounting bug in zoned mode. It happens when
a block group is switched back rw->ro and unusable bytes (due to
zoned constraints) are subtracted twice.

It has user visible effects so I consider it important enough for late
-rc inclusion and backport to stable.

Please pull, thanks.
