Subject: [PATCH] ASoC: rsnd: Add of_node_put() before return

Fix following coccicheck warning:
./sound/soc/sh/rcar/core.c:1223:1-23: WARNING: Function
for_each_child_of_node should have of_node_put() before return

Early exits from for_each_child_of_node should decrement the
node reference counter.
