I think we should initialize mpath_dev_found and mpath_dev_fallback to
NULL. Otherwise this may lead upto adding a junk mpath_device pointer
in ->current_path[node] when mpath_head->dev_list is empty. This may
particularly manifests when a controller is being shutdown and
concurrently I/O is forwarded to the same controller.
