udp: fix the proto value passed to ip_protocol_deliver_rcu for the segments
Guillaume noticed that: for segments udp_queue_rcv_one_skb() returns the
proto, and it should pass "ret" unmodified to ip_protocol_deliver_rcu().
Otherwize, with a negtive value passed, it will underflow inet_protos.
This can be reproduced with IPIP FOU:
# ip fou add port 5555 ipproto 4
# ethtool -K eth1 rx-gro-list on
Fixes: cf329aa42b66 ("udp: cope with UDP GRO packet misdirection")
