ALSA: hda: Drop useless WARN_ON()
BugLink: http://bugs.launchpad.net/bugs/1745069 commit a36c2638 upstream. Since the commit 97cc2ed2 ("ALSA: hda - Fix yet another i915 pointer leftover in error path") cleared hdac_acomp pointer, the WARN_ON() non-NULL check in snd_hdac_i915_register_notifier() may give a false-positive warning, as the function gets called no matter whether the component is registered or not. For fixing it, let's get rid of the spurious WARN_ON().
