cpufreq: Initialize cpufreq-based invariance before subsys

cpufreq: Initialize cpufreq-based invariance before subsys

commit 2a6c72738706 ("cpufreq: Initialize cpufreq-based
frequency-invariance later") postponed the frequency invariance
initialization to avoid disabling it in the error case.
This isn't locking safe, instead move the initialization up before
the subsys interface is registered (which will rebuild the
sched_domains) and add the corresponding disable on the error path.
