Title:
  Swapping volume will not result in correct status

Status in Cinder:
  Fix Committed
Status in OpenStack Compute (nova):
  New

Bug description:
  Swap volume API can swap a in-use volume with available volume.
  Therefore in-use volume should be available and available will be in-use.
  In face, volumes will stay in detaching and attaching respectively after send swap volume request to nova.
  But those volumes had been swapped.
  Following are commands flow.
