It is not really clear to me what you are trying to test.
This does not really test hierarchical quota, but just 3
independent quotas. To make them hierarchical, you have
to create higher level qgroups.

This is probably not the expected output, as the written data
did not show up yet. You should add a btrfs fi sync before the qgroup
show command to force the delayed writes to disk. Otherwise they're
not accounted for yet.
