initialize mtu/hlim for enc interface at encattach().
backgronud: inbound ipsec packet will have enc* as m->m_pkthdr.rcvif.
when we try to reflect the packet back in the kernel (like icmp6 echo),
we'd generate packet toward enc* interface. icmp6_reflect() will take
hoplimit value from nd_ifinfo[enc*], which was not initialized by the old code.
XXX the change to m->m_pkthdr.rcvif violates IPv6 scoped routing.
we will need to disable it, for at least IPv6.
