Fixing a regression (black screen) caused by a commit 92b58156e7
("ui/gtk: set scanout-mode right before scheduling draw").
The commit 92b58156e7 was made with an assumption that the scanout
mode needs to be set only if the guest scanout is a dmabuf but there
are cases (e.g. virtio-gpu-virgl) where the scanout is still processed
in a form of a texture but is not backed by dmabuf. So it is needed
to put back the line that sets scanout mode in gd_egl_scanout_texture
and gd_gl_area_scanout_texture.

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.
