gro: Fix potential use after free
The initial skb may have been freed after napi_gro_complete in napi_gro_receive if it was merged into an existing packet. Thus we cannot check same_flow (which indicates whether it was merged) after calling napi_gro_complete. This patch fixes this by saving the same_flow status before the call to napi_gro_complete.
