selftests: tracing: Enable fprobe events before checking enable_functions
Since the fprobe is not registered before enabling the fprobe events,
enable_functions is also empty before enabling it. Thus the tests
which checking enable_functions must ensure the event is enabled before
testing the enable_functions.
