ALSA: hda/i915 - avoid hung task timeout in i915 wait

Browse Source 
If kernel is built with hung task detection enabled and
CONFIG_DEFAULT_HUNG_TASK_TIMEOUT set to less than 60 seconds,
snd_hdac_i915_init() will trigger the hung task timeout in case i915 is
not available and taint the kernel.

Use wait_for_completion_killable_timeout() for the wait to
avoid this problem.
