    Fix stopping stopped instances

    Nova-compute would periodically sync the instance status. So in the
    instance failure recovery workflow,it would stop instance random failed
    because of conflict, which will terminate the recovery workflow.
    This patch can catch the Confict exception and continue the recovery
    workflow if the instance already stopped.
