The btrfs/022 test is basic test about qgroup. but it doesn't have
test with qgroup assign function. This patch adds parent assign
test. parent assign test make two subvolumes and a qgroup for assign.
Assign two subvolumes with a qgroup and check that quota of group
has same value with sum of two subvolumes.
