virtio-gpu: replace the surface with null surface when resetting
The primary guest scanout shows the booting screen right after reboot but additional guest displays (i.e. max_ouptuts > 1) will keep displaying the old frames until the guest virtio gpu driver gets initialized, which could cause some confusion. A better way is to to replace the surface with a place holder that tells the display is not active during the reset of virtio-gpu device. And to immediately update the surface with the place holder image after the switch, displaychangelistener_gfx_switch needs to be called with 'update == TRUE' in dpy_gfx_replace_surface when the new surface is NULL.
