Martin Wilck 93eb0381e1 nvme: multipath: round-robin: fix single non-optimized path case 
If there's only one usable, non-optimized path, nvme_round_robin_path()
returns NULL, which is wrong. Fix it by falling back to "old", like in
the single optimized path case. Also, if the active path isn't changed,
there's no need to re-assign the pointer.
