ndisc: don't update dad_counter for addresses in router config

I am not sure, we ever call complete_address() for router-configurations.
Maybe not, so the dad-counter is never incremented and does not matter either.

If we however do, then we certainly want to preserve the DAD counter
when the address is already tracked.
