[PATCH] cpufreq: schedutil: Fix self-contradictory comment in sugov_iowait_apply()

[Zhongqiu Han]

The kerneldoc of sugov_iowait_apply() says the IO boost value is increased
in sugov_iowait_apply() and, in the same sentence, that it is decreased by
the same function. That is self-contradictory, and the first part is wrong:
sugov_iowait_apply() only decreases the boost.

The boost is actually increased in sugov_iowait_boost(). Fix the comment to
name sugov_iowait_boost() as the place where the boost is increased, so it
matches the code.

No functional change.
