CP microcode uses undocumented bits in this register to record queue state information. The KFD zeroes these bits in update_mqd, when invoked through the UPDATE_QUEUE ioctl, causing incoherent state when the ioctl is used to successively unmap and map a queue. Since the queue type cannot be changed in this path, move the MQD write to init_mqd.
