The nvme_fc_unregister_localport() returns an error code in case that the locaport pointer is NULL or has already been unegisterd. localport is is either in the ONLINE state (all resources allocated) or has already been put into DELETED state. In this case we will never receive an wakeup call and thus any caller will hang, e.g. module unload.
