Bluetooth: btusb: Free driver data on USB shutdown
Instead of using the hci-destruct callback we free our private driver data on USB shutdown. We already called hci_unregister_dev() here so the hci core will never ever call our callbacks again except the destruct callback. However, there is no reason to keep our *private* driver data alive if we get never called again and the hci-core does never touch it the data. So we simply free it right away and set the destruct callback to NULL.
