ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai()

commit 419d191 ("ASoC: simple-card-utils: use __free(device_node) for
device node") uses __free(device_node) for dlc->of_node, but we need to
keep it while driver is in use.

Don't use __free(device_node) in graph_util_parse_dai().
