drm/i915/display: use max_level to control loop
Since we are already loop through the levels to sanitize them, mark what
is the real max_level so it can be used in subsequent loop. This makes
it simpler to later add the adjustment latency to "valid levels". No
change in behavior, just makes the code easier to follow.
