Bluetooth: Add a new workqueue for hci_request operations
The hci_request function is blocking and cannot be called through the usual per-HCI device workqueue (hdev->workqueue). While hci_request is in progress any other work from the queue, including sending HCI commands to the controller would be blocked and eventually cause the hci_request call to time out. This patch adds a second workqueue to be used by operations needing hci_request and thereby avoiding issues with blocking other workqueue users.
