powercap: intel_rapl_tpmi: Handle PMU registration failure during probe

intel_rapl_tpmi_probe() invokes rapl_package_add_pmu() but ignores its
return value, so a PMU registration failure would leave the driver
reporting probe success despite the PMU being absent, with no log
trace.

Since PMU registration is an optional auxiliary feature for perf energy
counters, its failure should not break the primary powercap functionality.
Check the return value and log a warning to ensure graceful degradation.
