[PATCH net-next 1/4] 6lowpan: remove unnecessary set of headers

[Alexander Aring <alex.aring-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

On receiving side we don't need to set any headers in skb because the
6LoWPAN layer do not access it. Currently these values will set twice
after calling netif_rx.
