Title:
  Fake instance stuck in MIGRATING state

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  I am using FakeDriver.

  It seems that when concurrent resize and live-migration operations, a
  fake instance can remain stucked in MIGRATING state.

  To reproduce the bug, I spawned a fake instance and run a script that resized it to random flavors every second. Concurrently, from another node, I run a script that tried to live-migrate the instance to another host (every 1.2 seconds).
  Most of the times messages were something like 'cannot migrate instance in state VERIFY_RESIZE', but, when live-migration succeeded the instance was stuck in MIGRATING status and needed a `nova refresh --active` command.
