ip6-nd: Solicitation reply only if target is our link-local
Type: fix
The fib source IP6_ND is used for all link-local entries, hence
solicitation responses were sent for a peer's address. Constrain the
source check to also in clude the LOCAL flag, which indicates that the
link-local address is ours.
