platform/x86: intel-uncore-freq: Conditionally create attribute for read frequency

Browse source

commit 4d73c6772a upstream.

When the current uncore frequency can't be read, don't create attribute
"current_freq_khz" as any read will fail later. Some user space
applications like turbostat fail to continue with the failure. So, check
error during attribute creation.
