[IPV4]: Remove unsupported DNAT (RTCF_NAT and RTCF_NAT) in IPV4
- The DNAT (Destination NAT) is not implemented in IPV4.
- This patch remove the code which checks these flags
in net/ipv4/arp.c and net/ipv4/route.c.
The RTCF_NAT and RTCF_NAT should stay in the header (linux/in_route.h)
because they are used in DECnet.
