commit 3c83ac23253c ("ASoC: hdac_hdmi: check error return") fixes
the static checker warning reported by Dan Carpenter:
sound/soc/codecs/hdac_hdmi.c:416 hdac_hdmi_parse_and_map_nid()
warn: unsigned 'hdac->num_nodes' is never less than zero.
But it doesn't fix the issue completely.
It's also a failure if no sub nodes found for an afg node. So modify
the return condition appropriately.
