This patch removes dev->gso_skb as it is no longer necessary with
batching code.

[NET_BATCH] kill dev->gso_skb
The batching code does what gso used to batch at the drivers.
There is no more need for gso_skb. If for whatever reason the
requeueing is a bad idea we are going to leave packets in dev->blist
(and still not need dev->gso_skb)
