tracing: Test the 'Do not trace this pid' case in create event
When creating a new event (via a module, kprobe, eprobe, etc), the descriptors that are created must add flags for pid filtering if an instance has pid filtering enabled, as the flags are used at the time the event is executed to know if pid filtering should be done or not. The "Only trace this pid" case was added, but a cut and paste error made that case checked twice, instead of checking the "Trace all but this pid" case.
