Taehee Yoo a70f891e0f net: devmem: do not WARN conditionally after netdev_rx_queue_restart() 
When devmem socket is closed, netdev_rx_queue_restart() is called to
reset queue by the net_devmem_unbind_dmabuf(). But callback may return
-ENETDOWN if the interface is down because queues are already freed
when the interface is down so queue reset is not needed.
So, it should not warn if the return value is -ENETDOWN.
