Re: [PATCH] perf/x86/core: Simplify hybrid PMU registration failure path

Handle perf_pmu_register() errors directly instead of breaking out of
the registration loop and checking the index separately. Reuse the loop
index i to unregister any previously registered PMUs in reverse order
and drop the extra index j.

Also log the failing PMU's name and error code.
