netfilter: fix tuple inversion for Node information request
The patch fixes a typo in the inverse mapping of Node Information request. Following draft-ietf-ipngwg-icmp-name-lookups-09, "Querier" sends a type 139 (ICMPV6_NI_QUERY) packet to "Responder" which answer with a type 140 (ICMPV6_NI_REPLY) packet.
