smack: Remove IPPROTO_UDPLITE support in security_sock_rcv_skb().
smack_socket_sock_rcv_skb() is registered as socket_sock_rcv_skb,
which is called as security_sock_rcv_skb() in sk_filter_trim_cap().
Now that UDP-Lite is gone, let's remove the IPPROTO_UDPLITE support
in smack_socket_sock_rcv_skb().
