gro: Restore correct value to gso_size
Since everybody has been focusing on baremetal GRO performance no one noticed when I added a bug that zapped gso_size for all GRO packets. This only gets picked up when you forward the skb out of an interface. Thanks to Mark Wagner for noticing this bug when testing kvm.
