[PATCH 4/4] virt-viewer-window: Don't try to resize non visible windows

[Hans de Goede <hdegoede@xxxxxxxxxx>]

Trying to resize not visible windows leads to the following being printed
to the console:
Gdk-CRITICAL **: IA__gdk_window_get_origin: assertion `GDK_IS_WINDOW (window)'

This gets triggered by the gdk_screen_get_monitor_geometry() call in
virt_viewer_window_resize()
