Subject: [PATCH] netfilter: nf_ct_udp: merge udpv[4,6]_net_init into
 udp_net_init

Merge udpv4_net_init and udpv6_net_init into udp_net_init to
remove redundant code now that we have the u_int16_t proto
parameter.

And use nf_proto_net.users to identify if it's the first time
we use the nf_proto_net, in that case, we initialize it.
