"Due to a CP interrupt bug, bad packet garbage exception codes are raised.
Do a range check so that the debugger and runtime do not receive garbage
codes.
Update the user api to guard exception code type checking as well."

"Here I think we should cancel work items that are still in the work
queue, not flush workqueue node->ih_wq. In this case the kfd functions
have been terminated, there is no way to handle the left work items.
That would make work queue flush never finish. I think it is the reason
there are orphan kernel tasks.
After cancel left work items we can call destroy_workqueue."
