perf: Fix perf probe build error

Fixes the following build error: util/probe-event.c:1266: attention : «ret» may be used uninitialized in this function util/probe-event.c:1266: note: «ret» was declared here Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Acked-by: Masami Hiramatsu <mhiramat@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> LKML-Reference: <1271808065-25290-1-git-send-regression-fweisbec@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
