cpufreq/amd-pstate: Reorder notifier unregistration and floor perf reset
An active power supply notifier can race with amd_pstate_epp_cpu_exit()
trying to reset the floor perf and can overwrite the floor perf set in
MSR_AMD_CPPC_REQ.
Unregister the notifier before setting the floor perf to prevent the
rare race.
