ipv6: don't count addrconf generated routes against gc limit
Brett Ciphery reported that new ipv6 addresses failed to get installed because the addrconf generated dsts where counted against the dst gc limit. We don't need to count those routes like we currently don't count administratively added routes. Because the max_addresses check enforces a limit on unbounded address generation first in case someone plays with router advertisments, we are still safe here.
