perf: Fix inherited events vs. tracepoint filters
Arnaldo reported that tracepoint filters seem to misbehave (ie. not
apply) on inherited events.
The fix is obvious; filters are only set on the actual (parent)
event, use the normal pattern of using this parent event for filters.
This is safe because each child event has a reference to it.
