  qxl: fix local renderer crash

Make sure we only ask the spice local renderer for display updates in
case we have a valid primary surface.  Without that spice is confused
and throws errors in case a display update request (triggered by
screendump for example) happens in parallel to a mode switch and hits
the race window where the old primary surface is gone and the new isn't
establisted yet.
