[PATCH] fstests: btrfs/224: do not assign snapshot to a subvolume qgroup

[Qu Wenruo <wqu@suse.com>]

For "btrfs subvolume snapshot -i <qgroupid>", we only expect the target
qgroup to be a higher level one.

Assigning a 0 level qgroup to another 0 level qgroup is only going to
cause confusion, and I'm planning to do extra sanity checks both in
kernel and btrfs-progs to reject such behavior.

So change the test case to do regular higher level qgroup assignment
only.
