fou: Don't allow 0 for FOU_ATTR_IPPROTO.
[ Upstream commit 7a9bc9e3f42391e4c187e099263cf7a1c4b69ff5 ]
fou_udp_recv() has the same problem mentioned in the previous
patch.
If FOU_ATTR_IPPROTO is set to 0, skb is not freed by
fou_udp_recv() nor "resubmit"-ted in ip_protocol_deliver_rcu().
Let's forbid 0 for FOU_ATTR_IPPROTO.
Fixes: 23461551c0062 ("fou: Support for foo-over-udp RX path")
