Public bug reported:
[Impact]
Kernel panic when doing rfkill block on Intel Bluetooth controller.
[Fix]
Ensure everything is stopped before calling the shutdown callback.
[Test]
Keep pressing the airplane mode button. High chance that a kernel splat
is shown and Bluetooth becomes unusable.
[Where problems could occur]
The shutdown callback is used by other Bluetooth controller as well.
Logically, the patch is doing the correct thing by queiscing the device
before calling shutodwn. However, other Bluetooth drivers may depend
it to behave correctly.
