Staging: batman-adv: Create copy of skb with pre-allocated headroom

Browse source

We can use skb_cow instead of a handwritten function to test and create
a writable skb buffer. This also allows us to pre-allocate headroom to
be able to send the data without re-allocating the buffer again to add
the ethernet header.
