[SK_BUFF] ipv6: More skb_reset_network_header conversions related to skb_pull
Now related to this form:
skb->nh.ipv6h = (struct ipv6hdr *)skb_put(skb, length);
That, as the others, is done when skb->tail is still equal to skb->data, making
the conversion to skb_reset_network_header possible.
Also one more case equivalent to skb->nh.raw = skb->data, of this form:
iph = (struct ipv6hdr *)skb->data;
<SNIP>
skb->nh.ipv6h = iph;
