When an xrun happens, the BE DAI hw_params doesn't get invoked before
the stream restarts with a prepare. In this case, clearing the node ID
when the DAI widget is freed and unprepared will result in an error when
it is re-initialized. In order to avoid this, move the code to clear the
node ID to the BE DAI hw_free op to keep it balanced with the BE DAI
hw_params.
