ALSA: fireface: fix for state to fetch PCM frames
According to my memo at hand and saved records, writing 0x00000001 to SND_FF_REG_FETCH_PCM_FRAMES disables fetching PCM frames in corresponding channel, however current implement uses reversed logic. This results in muted volume in device side during playback. This commit corrects the bug.
