David Ahern a1fd1ad255 ipv4: Pass original device to ip_rcv_finish_core ...

ip_route_input_rcu expects the original ingress device (e.g., for
proper multicast handling). The skb->dev can be changed by l3mdev_ip_rcv,
so dev needs to be saved prior to calling it. This was the behavior prior
to the listify changes.
