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
