l2tp: give proper headroom in pppol2tp_xmit() pppol2tp_xmit() calls skb_cow_head(skb, 2) before calling l2tp_xmit_skb() Then l2tp_xmit_skb() calls again skb_cow_head(skb, large_headroom) This patchs changes the first skb_cow_head() call to supply the needed headroom to make sure at most one (expensive) pskb_expand_head() is done.
