cpufreq: conservative: Break out earlier on the lowest frequency
If we're on the lowest frequency, no need to calculate new freq. Break out even earlier in this case. Signed-off-by: Namhyung Kim <namhyung@kernel.org> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
