Convert the "tos" parameter of ip_route_output() to dscp_t. This way
we'll have a dscp_t value directly available when .flowi4_tos will
eventually be converted to dscp_t.
All ip_route_output() callers but one set this "tos" parameter to 0 and
therefore don't need to be adapted to the new prototype.
Only br_nf_pre_routing_finish() needs conversion. It can just use
ip4h_dscp() to get the DSCP field from the IPv4 header.
