The encoder callbacks are only called in case the video mode changes. So any layout changes without mode changes will go unnoticed. Add qxl_crtc_update_monitors_config(), based on the old qxl_write_monitors_config_for_encoder() function. Hook it into the enable, disable and flush atomic crtc callbacks. Remove monitors_config updates from all other places.
