alsa-sink: Don't pretend to support passthrough on HDMI surround sinks

Browse source 
It doesn't work currently (fails and falls back to PCM), due to channel
count mismatch between the sink sample spec and the sample spec required
by IEC61937.

To be reverted when someone implements changing channel count without
switching profiles. This would also be required for HBR passthrough over
HDMI.
