[PATCH 4/4] misc: ti-st: st_kim: use 'time_left' variable with wait_for_completion_interruptible_timeout()

[Wolfram Sang]

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

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

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