Christophe Gisquet	adf4ee40e7	wma lossless: reuse scalarproduct_and_madd_int16 This is done by padding the coefficient buffer with 0s, because the order may be only a multiple of 4, and the DSP function requires batches of 8. However, no sample with such a case was found, so request one if it uses that kind of order.
