Title:
  Volume "in-use" although VM doesn't exist

Status in Cinder:
  Invalid
Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Setup:

  devstack on master using default settings.

  Steps:

    1) Using tempest/stress with patch https://review.openstack.org/#/c/36652/:
    cd /opt/stack/tempest/tempest/stress
    ./run_stress.py etc/volume-assign-delete-test.json -d 60
    2) Test will do the following work flow:
         - create a volume
         - create a VM
         - attach volume to VM
         - delete VM
         - delete volume

  Problem:

  Deletion of volume causes problem, since the state is still "in-use"
  even the VM is already deleted:
