migration debugfs needs to perform debug operations based on the status of the current device. If the device is not loaded or has stopped, debugfs does not allow operations.
so, after the live migration function is executed and the device is turned off, the device no longer needs to be accessed. At this time, the status of the device needs to be set to stop.
