audio/mixeng: fix sw/hw mixup in audio_pcm_sw_init_

Browse Source 
Commit 42061a1435 ("audio/mixeng: replace redundant pcm_info fields
with AudioFormat") accidentally changed the conv/clip function selection
in audio_pcm_sw_init_ to use hw->info.af (the hardware voice format)
instead of sw->info.af (the software voice format). This causes audio
distortion when the software and hardware voices use different formats,
as the wrong conversion functions are applied to the audio data.

Fix by using sw->info.af, restoring the original behavior.
