wireguard: prevent segfault on non-adj packets
An unexpected packet that shows up on a Wireguard interace
that happens not to have a forwarding peer will cause a
segfault trying to index the vector of peers by adjacency.
Rather than segfaulting, recognize a non-adjacent packet
and drop it instead.
This leaves open the question of what _should_ be
happening to, say, IPv6 multicast packets.
