ENGR00278967 ASoC: fsl: Fix null pointer when rmmod snd-soc-imx-hdmi
When rmmod snd-soc-imx-hdmi if loadable module feature of HDMI audio
is being used, there would be a kernel dump promt:
Unable to handle kernel NULL pointer dereference at virtual address
This was caused by inappropriate priv pointer fetching, thus fix it.
