soundwire: generic_bandwidth_allocation: count the bandwidth of activ…

…e 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(). Signed-off-by: Bard Liao <[email protected]>
