tcp: gro: micro optimizations in tcp[4]_gro_complete()
In tcp_gro_complete() :
Moving the skb->inner_transport_header setting
allows the compiler to reuse the previously loaded value
of skb->transport_header.
Caching skb_shinfo() avoids duplications as well.
In tcp4_gro_complete(), doing a single change on
skb_shinfo(skb)->gso_type also generates better code.
