Keith Packard 40dc81154a present: Avoid crash at server shutdown ...

When a present flip operation is still in process during server reset,
the call to present_set_abort_flip may not happen until the screen is
being closed, at which point there is no root window to set pixmaps
for. Check to make sure there's a window before resetting window pixmaps.
