ASoC: simple-card-utils: Check device node before overwrite direction 

Even the device node don't exist, the graph_util_parse_link_direction()
will overwrite the playback_only and capture_only to be zero. Which
cause the playback_only and capture_only are not correct, so check device
node exist or not before update the value.
