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.
