In multi-queue hang mode, a reset of any queue in a queue group will
cause the entire group to reset. And since GuC only submits on the
primary queue, without explicit barriers or priority differences
between queues, we can't guarantee which queue hardware will pick up
on submission. As such, we don't know which queues will complete
prior to the group reset and need to check for all possible values.
