ASoC: codecs: wcd934x: Add missing of_node_put() in wcd934x_codec_parse_data

[ Upstream commit 9531a631379169d57756b2411178c6238655df88 ]

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.
This is similar to commit 64b92de9603f
("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put")
