ospf6d: don't suppress empty router LSA

Currently in OSPFv3 implementation, if all the interfaces are down/loopback
or are without any full adjacencies, the router LSA is suppressed. So for
a router with only stub networks, no router LSA is generated. However,
intra-prefix LSAs are generated for the stub networks and these intra-prefix
LSAs will reference the router LSA. So the router LSA really should not be
suppressed. It needs to be generated to be the starting vertex for SPF
w.r.t the stub networks.
