[virt-tools-list] [PATCH virt-viewer 1/4] Remove warning when removing display

[Marc-André Lureau]

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

Some display have no associated window (for ex, if it doesn't fit
on client monitors).

(remote-viewer:22275): remote-viewer-CRITICAL **: virt_viewer_window_set_display: assertion `VIRT_VIEWER_IS_WINDOW(self)' failed

(remote-viewer:22275): remote-viewer-CRITICAL **: virt_viewer_app_remove_nth_window: assertion `win != NULL' failed
