We don't need to prepare the stream again if the stream is already prepared. sdw_prepare_stream() could be called multiple times without calling sdw_deprepare_stream(). We call sdw_prepare_stream() in the prepare dai ops and sdw_deprepare_stream() in the hw_free dai ops. If an xrun happens, sdw_prepare_stream() will be called but sdw_deprepare_stream() will not, which results in an imbalance and an invalid total bandwidth.
