Subject: ALSA: hda - Fix yet another i915 pointer leftover in error path

From: Takashi Iwai <tiwai@suse.de>

commit 97cc2ed27e5a168cf423f67c3bc7c6cc41d12f82 upstream.

The hdac_acomp object in hdac_i915.c is left as assigned even after
binding with i915 actually fails, and this leads to the WARN_ON() at
the next load of the module.
