[82/89] CPUFREQ: Remove cpufreq_stats sysfs entries on module unload.

[Greg KH]

2.6.39-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Dave Jones <davej@xxxxxxxxxx>

commit 13f067537f34456443f61c950cd6dc37d1d5f3ee upstream.

cpufreq_stats leaves behind its sysfs entries, which causes a panic
when something stumbled across them.
(Discovered by unloading cpufreq_stats while powertop was loaded).
