spice: stop server for qxl hard reset

Browse Source 
Hard reset can happen at any time.  We should be able to put qxl into a
known-good state no matter what.  Stop spice server thread for reset so
it can't be confused by fetching stale commands lingering around in the
rings while we reset is ongoing.
