ALSA: hda - Clear the leftover component assignment at snd_hdac_i915_exit()
commit faafd03d23c913633d2ef7e6ffebdce01b164409 upstream.
The commit [d745f5e7b8b2: ALSA: hda - Add the pin / port mapping on
Intel ILK and VLV] introduced a WARN_ON() to check the pointer for
avoiding the double initializations. But hdac_acomp pointer wasn't
cleared at snd_hdac_i915_exit(), thus after reloading the HD-audio
driver, it may result in the false positive warning. This patch makes
sure to clear the leftover pointer at exit.
