On some systems btrfs/179 fails because the check finds that there is
difference in the qgroup counts.
So as the intention of the test case is to test any hang like situation
during heavy snapshot create/delete operation with quota enabled, so
make sure the qgroup counts are consistent at the end of the test case,
so to make the check happy.

v2: Use subvolume sync at the end of the test case.
