bgpd: Workaround for invalid MBGP next hop
* bgp_attr.c: (bgp_mp_reach_parse) There are some interoperability issues
for MBGP (particularly IPv4 multicast NLRI) between different
implementations. In order to get some next hops to install correctly in
the BGP tables, it appears to be necessary to copy the multiprotocol next
hop into the base next hop field. This is related to differences in RFC
2283 and RFC 2858.
