soundwire: generic_bandwidth_allocation: count the bandwidth of active streams only
sdw_compute_group_params() should only count payload bandwidth of the
active streams which is in the ENABLED and DISABLED state in the bus.
And add the payload bandwidth of the stream that calls
sdw_compute_group_params() in sdw_prepare_stream().
