tracing: Fix build breakage without CONFIG_PERF_EVENTS (again)
Today's -next fails to link for me:
kernel/built-in.o:(.data+0x178e50): undefined reference to `perf_ftrace_event_register'
It looks like multiple fixes have been merged for the issue fixed by
commit fa73dc9 (tracing: Fix build breakage without CONFIG_PERF_EVENTS)
though I can't identify the other changes that have gone in at the
minute, it's possible that the changes which caused the breakage fixed
by the previous commit got dropped but the fix made it in.
