wifi: ath11k: use 'time_left' variable with wait_event_timeout()

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

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

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

Fix to the proper variable type 'long' while here.
