esp4: Avoid skb_cow_data whenever possible
This patch tries to avoid skb_cow_data on esp4. On the encrypt side we add the IPsec tailbits to the linear part of the buffer if there is space on it. If there is no space on the linear part, we add a page fragment with the tailbits to the buffer and use separate src and dst scatterlists. On the decrypt side, we leave the buffer as it is if it is not cloned. With this, we can avoid a linearization of the buffer in most of the cases.
