Title:
  adding default bdms is considering instances as volume backed

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  There was a recent change in nova-api to add bdms for all instances. The device_name would be NULL by default
  Instances with root_device_name as NULL are all considered to be volume backed instances because of the check

  instance[root_device_name] == bdm[device_name]

  We have to handle the scenario where they are NULL and return False.
