KVM: x86/pmu: Refactoring find_arch_event() to pmc_perf_hw_id()
The find_arch_event() returns a "unsigned int" value, which is used by the pmc_reprogram_counter() to program a PERF_TYPE_HARDWARE type perf_event. The returned value is actually the kernel defined generic perf_hw_id, let's rename it to pmc_perf_hw_id() with simpler incoming parameters for better self-explanation.
