[PATCH 4/4] ASoC: codecs: wm8996: use 'time_left' variable with wait_for_completion_timeout()

[Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>]

There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:

	timeout = wait_for_completion_timeout(...)
	if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.
