ASoC: samsung: Fix error handling in aries_audio_probe
[ Upstream commit 3e2649c5e8643bea0867bb1dd970fedadb0eb7f3 ] of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. This function is missing of_node_put(cpu) in the error path. Fix this by goto out label. of_node_put() will check NULL pointer.
