[virt-tools-list] [PATCH 12/22] display: ignore display that do not have toplevel window

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

virt_viewer_display_get_preferred_monitor_geometry() may be called
during application initialization (when the VTE console is being
shown, virt_viewer_session_update_displays_geometry() is called when
the visibility menu item is toggled). But the other displays may not
yet be associated with a window, ignore them.
