tcp: Set route scope properly in cookie_v4_check().
RT_CONN_FLAGS(sk) overloads flowi4_tos with the RTO_ONLINK bit when
sk has the SOCK_LOCALROUTE flag set. This allows
ip_route_output_key_hash() to eventually adjust flowi4_scope.
Instead of relying on special handling of the RTO_ONLINK bit, we can
just set the route scope correctly. This will eventually allow to avoid
special interpretation of tos variables and to convert ->flowi4_tos to
dscp_t.
