v4l2_ctrl_handler_free() and v4l2_device_unregister() are currently only called when the last user closes the device and the device is already disconnected. But that's wrong, we need to call these functions whenever the em28xx-v4l extension is closed and we can already do this if the device is still opened by some users.
