For bw higher than 20 MHz ACS request, such as 160 MHz, weight calculation will combine the neighbor channel's weight which maybe Non PSC channel, the previous setting of combined weight to channel of lowest weight of neighbor channel. That maybe Non PSC channel, that causes the final ACS result is Non PSC channel, which is unexpected for standalone SAP. Fix by set combined weight to PSC channel, so that PSC channel will have a valid weight in final sorting with 5 GHz or 2 GHz list.
