Are you sure this works properly with simultaneous record and playback?
If one stops while the other is running then the configured flag will be
cleared, meaning that the stopped stream can be restarted and used to
reconfigure the DAI which appears to be what the code is trying to
prevent.
This should be using constraints to stop applications trying to
reconfigure active streams - for the sample rate you just need to set
symmetric_rates in the DAI.
