soundwire: stream: restore cumulative bus bandwidth when compute_params callback...

The _sdw_prepare_stream function just returns the error code when
compute_params callback failed.
The cumulative bus bandwidth will keep the value and won't be decreased
by sdw_deprepare_stream function.
We should restore the value of cumulative bus bandwidth when
compute_params callback failed.
