We just made sure policy->cpu is online and this check will always fail
as the policy is active. Drop it.

I didn't give a clear ack/review for the series. So, to clarify my 
ack/review

For all patches except 4/5, I'm okay with either/all of this:
Reviewed-by:  Saravana Kannan <skannan@codeaurora.org>
Acked-by: Saravana Kannan <skannan@codeaurora.org>

For 4/5, I would still like us to move the sysfs creating after init. 
That part shouldn't be too hard. We don't need to create the sysfs file 
before init.

Once that's done, I wouldn't mind giving an Ack.

Thanks,
Saravana
