When removing a listener, there's a small window when the listener is
already freed, while the controllers that were created on that listener
are still active. It happens, because the listener is removed before
disconnecting its qpairs and in turn destroying the controllers.
The ctrlr->listener pointer is now cleared when a listener is freed and
its value is checked for NULL before each use.
