ospf6d: handle redistributed routes without nexthop addresses
Do not assume that all redistributed routes have a nexthop address,
otherwise blackhole nexthops can be misinterpreted as IPv6 addresses,
leading to inconsistencies.
Also, change the signature of a few functions to allow const nexthop
addresses, such that in6addr_any can be used without type casts.
