Subject: [PATCH] perf: Fix perf probe build error

When we run into dry run mode, we want to make write_kprobe_trace_event
to succeed on writing the event. Let's initialize it to 0.

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
