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.

Changes V2->V3:
 - drop the loop and just use 
   wait_for_completion_killable_timeout() (feedback from Tvrtko Ursulin)
 - new approach, so dropped the previous reviewed-by tags
