ANDROID: Fix kenelci build-break for !CONFIG_PERF_EVENTS

Browse Source 
Kernelci builds were broken if !CONFIG_PERF_EVENTS since 467eb53acd ("ANDROID: cpu/hotplug:
avoid breaking Android ABI by fusing cpuhp steps") causes
perf_event_init_cpu(cpu) to be reduced to "NULL(cpu)":

kernel/cpu.c:1868:21: error: called object type 'void *' is not a function or function pointer

Fixes: 467eb53acd ("ANDROID: cpu/hotplug: avoid breaking Android ABI by fusing cpuhp steps")
