netfilter: nf_dup4: Convert nf_dup_ipv4_route() to dscp_t. 



Use ip4h_dscp() instead of reading iph->tos directly.

ip4h_dscp() returns a dscp_t value which is temporarily converted back
to __u8 with inet_dscp_to_dsfield(). When converting ->flowi4_tos to
dscp_t in the future, we'll only have to remove that
inet_dscp_to_dsfield() call.
