This test was reproducing a bug triggered by creating a subvolume qgroup
before creating the subvolume itself with a snapshot.
The kernel patch:
btrfs: forbid creating subvol qgroups
explicitly prevents that and makes it fail with EINVAL. I could "fix"
this test by expecting the EINVAL message in the output, but at that
point it would simply be a test that creating a subvolume and
snapshotting it works with qgroups, which is adequately tested by other
tests which focus on accurately measuring shared/exclusive usage in
various snapshot/reflink scenarios. To avoid confusion, I think it is
best to simply delete this test.
