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.
