perf: Fix hlist related build error 



hlist helpers need to be available for all software events, not
only trace events.

Pull them out outside the ifdef CONFIG_EVENT_TRACING section.

Fixes:
	kernel/perf_event.c:4573: error: implicit declaration of function 'swevent_hlist_put'
	kernel/perf_event.c:4614: error: implicit declaration of function 'swevent_hlist_get'
	kernel/perf_event.c:5534: error: implicit declaration of function 'swevent_hlist_release
