[PATCH v2 1/2] ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai()

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

commit 419d1918105e ("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().

Fixes: 419d1918105e ("ASoC: simple-card-utils: use __free(device_node) for device node")
