dccp: use inet6_csk_route_req() helper
Before changing dccp_v6_request_recv_sock() sock argument
to const, we need to get rid of security_sk_classify_flow(),
and it seems doable by reusing inet6_csk_route_req() helper.
We need to add a proto parameter to inet6_csk_route_req(),
not assume it is TCP.
