ASoC: wm8996: match wait_for_completion_timeout return type 

return type of wait_for_completion_timeout is unsigned long not int. An
appropriately named unsigned long is added and the assignment fixed up
in case of completion occurring the remaining time is >=1 so ret is set to
1 if no timeout occurred.
