[ Upstream commit 92548b0ee220e000d81c27ac9a80e0ede895a881 ]
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
