BGPD: Prevent IPv6-LL being fwd to IBGP peers not on same link.
Prevent IPv6 Link-local address being forward to IBGP peer,
which are not directly connected.
R1----IPV6-unnumbered-EBGP-------R2-----IPV6-IBGP-----R3
Configure route-map to set preferred global address on and apply
route-map-IN on R2 for R1-R2 session. Now check on R3's BGP and
RIB table has route nexthop as R1 link-local address, which is
not correct.
As of now we clear link-local address info from mp_nexthop_global,
only if mp_nexthop_global is populated with link-local address.
We should do it even if route-map is configured boz forwarding
link-local address from one link scope to another is violation of
the standards.
