Title:
  Poll rescued instances fails with key error

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  After an instance has been in the rescue state for some time, a periodic task triggers to unrescue the instances:
  _poll_rescued_instances

  File nova/notifications.py info_from_instance
    instance_type = flavors.extract_flavor(instance_ref)
  File "nova/compute/flavors.py" in extract_flavor
    instance_type[key] = type_fn(sys_meta[type_key])
  KeyError: 'instance_type_memory_mb'

  This then continues to happen on every run of the periodic task, and
  starts to fill up the DB with instance faults.
