[IPSEC]: Set skb->data to payload in x->mode->output
This patch changes the calling convention so that on entry from
x->mode->output and before entry into x->type->output skb->data
will point to the payload instead of the IP header.
This is essentially a redistribution of skb_push/skb_pull calls
with the aim of minimising them on the common path of tunnel +
ESP.
It'll also let us use the same calling convention between IPv4
and IPv6 with the next patch.
