[ This is a fix specific to 4.4.y and 4.9.y stable trees;
  4.14.y and older are not affected ]

The of-node refcount fixes were made in commit 8d166720 ("ASoC: qcom:
Fix of-node refcount unbalance in apq8016_sbc_parse_of()"), but not enough
in 4.4.y and 4.9.y. The modification of link->codec_of_node is missing.
This fixes of-node refcount unbalance to link->codec_of_node.
