[CPUFREQ] Missing "unregister_cpu_notifier" in powernow-k8.c

Browse source

It appears that when powernow-k8 finds that

    No compatible ACPI _PSS objects found.

 and suggests

    Try again with latest BIOS.

 it fails the module load, but does not unregister the cpu_notifier that was
 registered in powernowk8_init

 This ends up leaving freed memory on the cpu notifier list for some other
 poor module (e.g. md/raid5) to come along and trip over.

 The following might be a partial fix, but I suspect there is probably other
 clean-up that is needed.
