commit a514d63882c3 ("btrfs: qgroup: Commit transaction in advance to
reduce early EDQUOT") tries to reduce the early EDQUOT problems by
checking the qgroup free against threshold and try to wake up commit
kthread to free some space.
The problem of that mechanism is, it can only free qgroup per-trans
metadata space, can't do anything to data, nor prealloc qgroup space.
Now since we have the ability to flush qgroup space, and implements
retry-after-EDQUOT behavior, such mechanism is completely replaced.
So this patch will cleanup such mechanism in favor of
retry-after-EDQUOT.
