perf/x86: Fix sparse warnings

FYI, there are new sparse warnings:

 arch/x86/kernel/cpu/perf_event.c:1356:18: sparse: symbol 'events_attr' was not declared. Should it be static?

This patch makes it static and also adds the static keyword to
fix arch/x86/kernel/cpu/perf_event.c:1344:9: warning: symbol
'events_sysfs_show' was not declared.
