Akihiro Motoki eeb614c477 volume functest: ensure snapshots deleted when volume delete
Deleting snapshot may take time. The current volume API does not allow
to delete volumes with snapshots, so if deleting snapshot may take time,
a delete request for a parent volume will fail.
This sometimes causes functional test failures in slow environments.

wait_for_status() checks whether volume status is in error statuses
but previously the expected error status was wrong. Cinder API uses
lower case as volume status, so it did not work expectedly.
