sunrpc: do not pull udp headers on receive

Browse Source 
Commit e6afc8ace6 modified the udp receive path by pulling the udp
header before queuing an skbuff onto the receive queue.

Sunrpc also calls skb_recv_datagram to dequeue an skb from a udp
socket. Modify this receive path to also no longer expect udp
headers.

Fixes: e6afc8ace6 ("udp: remove headers from UDP packets before queueing")
