staging: vt6656: Use sk_buff buffer for tx header
mac80211 can provide space for the driver to put a tx header on
the skb buffer instead coping the entire frame on to a local
buffer with the header.
To use this extra_tx_headroom must be set in mac80211 with the largest
possible header which is struct vnt_tx_buffer.
The driver has 8 possible combinations of tx header size which
are found in vnt_get_hdr_size replacing vnt_mac_hdr_pos.
