net: netdev_alloc_skb() use build_skb()
netdev_alloc_skb() is used by networks driver in their RX path to
allocate an skb to receive an incoming frame.
With recent skb->head_frag infrastructure, it makes sense to change
netdev_alloc_skb() to use build_skb() and a frag allocator.
This permits a zero copy splice(socket->pipe), and better GRO or TCP
coalescing.

Though it does not seem to be simple revert to test this against current
master. It seems there should be a way for the driver to enforce the old
style somehow...
