ASoC: qcom: Fix missing of_node_put() in asoc_qcom_lpass_cpu_platform_probe()

[ Upstream commit d6d306560fa3e3b8e74fd63205dd21730dd6f951 ]

We should call of_node_put() for the reference 'dsp_of_node' returned by
of_parse_phandle() which will increase the refcount.

Fixes: 41d9a7422b1e ("ASoC: qcom: move ipq806x specific bits out of lpass driver.")
