However, before qxl_crtc_disable() is reached after the hotplug event, it can happen that another monitor is reconfigured, and qxl_send_monitors_config() is called with the old config, which will re-enable the monitor on the client. Reset config if monitor is found disconnected, during drm_helper_hpd_irq_event().
