Subject: [PATCH] cpufreq/schedutil: When updating limitations, frequency modulation interval not become invalid.

If the current frequency scaling policy is schedutil.
echo schedutil > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
This would result in an invalid frequency modulation interval.
In sugov_limit(), sg_policy->limits_changed is set to true.
