Follow-up Comment #1:

Thanks Stian.

I think in general the ->isrouter field protects that router entry. The only
time I see this could fail is if we get a RA message, but then router does not
respond to probe messages (highly unlikely).

So I think as a safety measure we should add to
nd6_free_neighbor_cache_entry() a check to remove a router if referenced.
