[PATCH net-next] dccp: Prepare dccp_v4_route_skb() to .flowi4_tos conversion.

Use inet_sk_dscp() to get the socket DSCP value as dscp_t, instead of
ip_sock_rt_tos() which returns a __u8. This will ease the conversion
of fl4->flowi4_tos to dscp_t, as it will just require to drop the
inet_dscp_to_dsfield() call.
