bpf: lwtunnel: Prepare bpf_lwt_xmit_reroute() to future .flowi4_tos conversion.
Use ip4h_dscp() to get the DSCP from the IPv4 header, then convert the dscp_t value to __u8 with inet_dscp_to_dsfield(). Then, when we'll convert .flowi4_tos to dscp_t, we'll just have to drop the inet_dscp_to_dsfield() call.
