tracing/events: don't say hi when loading the trace event sample

The sample is useful for testing, and I'm using it. But after
loading the module, it keeps saying hi every 10 seconds, this may
be disturbing.

Also Steven said commenting out the "hi" helped in causing races. :)

[ Impact: make testing a bit easier ]
