Gerd Hoffmann 8ec1415935 vfio: fix use-after-free in display 
Calling ramfb_display_update() might replace the DisplaySurface with the
boot display, which in turn will free the currently active
DisplaySurface.

So clear our DisplaySurface pinter (dpy->region.surface pointer) to (a)
avoid use-after-free and (b) force replacing the boot display with the
real display when switching back.
