[SK_BUFF]: More skb_reset_transport_header conversions
These are a bit more subtle, they are of this type:
- skb->h.raw = payload;
__skb_pull(skb, payload - skb->data);
+ skb_reset_transport_header(skb);
__skb_pull results in:
skb->data = skb->data + payload - skb->data;
skb->data = payload;
So after __skb_pull we have skb->data pointing to payload and we can
just call skb_reset_transport_header(skb), that will do:
skb->h.raw = payload;
The others are similar, allowing us to get rid of some more cases where a
pointer was being attributed to the layer headers.
