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.
