rxe_net.c sends packets at the IP layer with skb->data
pointing at the IP header but receives packets from
a UDP tunnel with skb->data pointing at the UDP header.
On the loopback path this was not correctly accounted for.
This patch corrects for this by using sbk_pull() to
strip the IP header from the skb on received packets.
