BFD: Dispatch sessions also by interface index

Direct BFD sessions needs to be dispatched not only by IP addresses, but
also by interfaces, in order to avoid collisions between neighbors with
the same IPv6 link-local addresses.

Extend BFD session hash_ip key by interface index to handle that. Use 0
for multihop sessions.

Thanks to Sebastian Hahn for the original patch.
