ASoC: Fix bias power down of non-DAPM codec
Currently bias of non-DAPM codec will be powered down (standby/off) whenever there is a stream stop. This is wrong in simultaneous playback/capture since the bias is put down immediately after stopping the first stream. Fix this by using the codec->active count when figuring out the needed bias level after stream stop.
