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().
