netpoll: fix rx_hook() interface by passing the skb
Right now skb->data is passed to rx_hook() even if the skb has not been linearised and without giving rx_hook() a way to linearise it. Change the rx_hook() interface and make it accept the skb and the offset to the UDP payload as arguments. rx_hook() is also renamed to rx_skb_hook() to ensure that out of the tree users notice the API change. In this way any rx_skb_hook() implementation can perform all the needed operations to properly (and safely) access the skb data.
