MES ADD_QUEUE programs the firmware with the queue type from the driver input, but MES REMOVE_QUEUE leaves queue_type at the zero-initialized value. Zero decodes as GFX in the MES REMOVE_QUEUE packet. That means removing a KFD compute queue can be submitted to MES as a GFX queue. In a debug-trap suspend/remove sequence this can leave MES looking for the doorbell in the wrong queue class and the REMOVE_QUEUE command may never complete. The observed failing packet removed doorbell 0x1002 with queue_type=GFX even though the corresponding ADD_QUEUE for the same doorbell was queue_type=COMPUTE. Populate REMOVE_QUEUE.queue_type the same way ADD_QUEUE does.
