Bluetooth: Re-order clearing suspend tasks 

Unregister_pm_notifier is a blocking call so suspend tasks should be
cleared beforehand. Otherwise, the notifier will wait for completion
before returning (and we encounter a 2s timeout on resume).

Fixes: 0e9952804e (Bluetooth: Clear suspend tasks on unregister)
