The initialization function used by hci_open_dev (hci_init_req) sends
many different HCI commands. The __hci_request function should only
return when all of these commands have completed (or a timeout occurs).
Several of these commands cause hci_req_complete to be called which
causes __hci_request to return prematurely.

This patch fixes the issue by adding a new hdev->req_last_cmd variable
which is set during the initialization procedure. The hci_req_complete
function will no longer mark the request as complete until the command
matching hdev->req_last_cmd completes.

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.
