drm/qxl: fix disabling extra monitors from client
To disable a monitor, a Spice client sends a monitor config with the monitor resolution to 0x0. 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(). Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
