drm/amdkfd: Preserve CP_MQD_IQ_RPTR internal state
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.
