    cpufreq: fix notifier block double registration
    
    As a consequence of commit 49388f11d512bb92706ce
    ("x86/cpufreq: relocate the driver register function")
    the cpufreq CPU notifier was being registered twice.
    That resulted in bugs when trying to offline a
    CPU, as reported here:
