netfilter: fix tuple inversion for Node information request

Browse source 
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.
