ipv4: fix endianness issue in inet_rtm_getroute_build_skb()
The UDP length field should be in network order.
This removes the following sparse error:
net/ipv4/route.c:3173:27: warning: incorrect type in assignment (different base types)
net/ipv4/route.c:3173:27: expected restricted __be16 [usertype] len
net/ipv4/route.c:3173:27: got unsigned long
Fixes: 404eb77ea766 ("ipv4: support sport, dport and ip_proto in RTM_GETROUTE")
