gro: Only use skb_gro_header for completely non-linear packets
Currently skb_gro_header is used for packets which put the hardware
header in skb->data with the rest in frags. Since the drivers that
need this optimisation all provide completely non-linear packets,
we can gain extra optimisations by only performing the frag0
optimisation for completely non-linear packets.
In particular, we can simply test frag0 (instead of skb_headlen)
to see whether the optimisation is in force.
