In certain situations, the sysfs for uncore may not be present when all CPUs in a package are offlined and then brought back online after boot.

Thank you for your contribution, it has been applied to my local review-ilpo-fixes branch. Note it will show up in the public platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my local branch there, which might take a while.
