networking: introduce and use skb_put_data()
A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.
An spatch similar to the one for skb_put_zero() converts many
of the places using it:

identifier p, p2;
expression len, skb, data;
type t, t2;

(
-p = skb_put(skb, len);
+p = skb_put_data(skb, data, len);

+skb_put_data(skb, data, len);
