[PATCH v2 08/17] audio: remove unused noop_conv() function

["Volker Rümelin" <vr_qemu@t-online.de>]

The function audio_capture_mix_and_clear() no longer uses
audio_pcm_sw_write() to resample audio frames from one internal
buffer to another. For this reason, the noop_conv() function is
now unused. Remove it.
