Remove debug messages from VbAudioLooping() - too noisy.

The VBDEBUG() is logged even for production builds (visible as
/sys/firmware/log once the system boots). Too many messages clutter it up.

BUG=chrome-os-partner:7669
TEST=manual

Boot in dev-mode, log in and look at /sys/firmware/log. You shouldn't see
more than dozen lines or so of VbAudio debug messages.
