perf/events/amd/uncore: Fix amd_uncore_llc ID to use pre-defined cpu_llc_id

Current logic iterates over CPUID Fn8000001d leafs (Cache Properties)
to detect the last level cache, and derive the last-level cache ID.
However, this information is already available in the cpu_llc_id.
Therefore, make use of it instead.
