[IPV4] udp: trim forgets about CHECKSUM_HW
A UDP packet may contain extra data that needs to be trimmed off. But when doing so, UDP forgets to fixup the skb checksum if CHECKSUM_HW is being used. I think this explains the case of a NFS receive using skge driver causing 'udp hw checksum failures' when interacting with a crufty settop box.
