[PATCH 3/3] nvme-rdma: don't fully stop the controller in error recovery

[Sagi Grimberg]

By calling nvme_stop_ctrl on a already failed controller will
wait for the scan work to complete (only by identify timeout
expiration which is 60 seconds). This is unnecessary when we
already know that the controller has failed.
