CHROMIUM: ALSA: hda/ca0132: Stop streaming when turning on/off Crystal Voice.

Similar to the previous fix for switching between microphones, if an
active recording stream is running, it has to be stopped before turning
on/off Crystal Voice, otherwise the parameters won't be applied correctly.

The patch is provided by Creative.

BUG=chrome-os-partner:14920
TEST=use "arecord -f cd -B 10000 -d 20 1.wav"
to record audio, and plug/unplug headphone while recording.
