ng_nat: Pass IPv6 packets through.
ng_nat implements NAT for IPv4 traffic only. When connected to an
ng_ether node it erroneously handled IPv6 packets as well.
This change is not sufficient: ng_nat does not do any validation of IP
packets in this mode, even though they have not yet passed through
ip_input().
