Bluetooth: Make hci_send_to_sock usable for management control sockets
In order to send data to management control sockets the function should: - skip checks intended for raw HCI data and stack internal events - make sure RAW HCI data or stack internal events don't go to management control sockets In order to accomplish this the patch adds a new member to the bluetooth skb private data to flag skb's that are destined for management control sockets.
