PM / devfreq: Fix kernel warning with cpufreq passive register fail

Remove cpufreq_passive_unregister_notifier from
cpufreq_passive_register_notifier in case of error as devfreq core
already call unregister on GOV_START fail.

This fix the kernel always printing a WARN on governor PROBE_DEFER as
cpufreq_passive_unregister_notifier is called two times and return
error on the second call as the cpufreq is already unregistered.
