[PATCH] ALSA: hda: Fix unused variable warning

[Takashi Iwai <tiwai@xxxxxxx>]

The previous code cleanup made a variable not really used, which now
leads to a compile warning.  Let's fix it.

Fixes: cac99f73f075 ("ALSA: hda: intel: Don't free interrupt when suspending")
Reported-by: kernel test robot <lkp@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-kbuild-all/202411050247.3esQz7Am-lkp@xxxxxxxxx/
