    Fix use-after-free in _XReply on X errors.
    
    _XReply would always call dequeue_pending_request on errors.  When it
    got an error for the current request, it would call dequeue, then break
    out of the loop; then, if it had an error in the event queue, it would
    compare it with the sequence number of the now-freed pending request.
    _XReply already stored that sequence number in dpy->last_request_read
    before freeing it, so look at that instead.
