[Bluetooth]: Move packet type into the SKB control buffer
This patch moves the usage of packet type into the SKB control buffer. After this patch it is now possible to shrink the sk_buff structure and redefine its pkt_type. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S. Miller <davem@davemloft.net>
