ipv4: Move IN_DEV_IGNORE_ROUTES_WITH_LINKDOWN to helper in_dev lookup followed by IN_DEV_IGNORE_ROUTES_WITH_LINKDOWN check is called in several places, some with the rcu lock and others with the rtnl held. Move the check to a helper similar to what IPv6 has. Since the helper can be invoked from either context use rcu_dereference_rtnl to dereference ip_ptr.
