perf/x86: Fixup typo in stub functions

Guenter reported a build warning for CONFIG_CPU_SUP_INTEL=n:

  > With allmodconfig-CONFIG_CPU_SUP_INTEL, this patch results in:
  >
  > In file included from arch/x86/events/amd/core.c:8:0:
  > arch/x86/events/amd/../perf_event.h:1036:45: warning: ‘struct cpu_hw_event’ declared inside parameter list will not be visible outside of this definition or declaration
  >  static inline int intel_cpuc_prepare(struct cpu_hw_event *cpuc, int cpu)

While harmless (an unsed pointer is an unused pointer, no matter the type)
it needs fixing.
