    ironic: check fresh data when sync_power_state doesn't line up

    We return cached data to sync_power_state to avoid pummeling the ironic
    API. However, this can lead to a race condition where an instance is
    powered on, but nova thinks it should be off and calls stop(). Check
    again without the cache when this happens to make sure we don't
    unnecessarily kill an instance.
