[XFRM]: esp: fix skb_tail_pointer conversion bug
Fix incorrect switch of "trailer" skb by "skb" during skb_tail_pointer
conversion:
- *(u8*)(trailer->tail - 1) = top_iph->protocol;
+ *(skb_tail_pointer(skb) - 1) = top_iph->protocol;
- *(u8 *)(trailer->tail - 1) = *skb_network_header(skb);
+ *(skb_tail_pointer(skb) - 1) = *skb_network_header(skb);
