net: ipv6: check route protocol when deleting routes
The protocol field is checked when deleting IPv4 routes, but ignored for IPv6, which causes problems with routing daemons accidentally deleting externally set routes (observed by multiple bird6 users). This can be verified using `ip -6 route del <prefix> proto something`. Signed-off-by: Mantas Mikul─Śnas <grawity@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
