Adrian Hunter 45210e1ada perf dlfilter: Avoid leak in v0 API test use of resolve_address() 
The introduction of reference counting causes the v0 API
perf_dlfilter_fns.resolve_address() to leak.

v2 API introduced perf_dlfilter_fns.al_cleanup() to prevent that.

For the v0 API, avoid the leak by exiting the addr_location immediately,
since the documentation makes it clear that pointers obtained via
perf_dlfilter_fns are not necessarily valid (dereferenceable) after
'filter_event' and 'filter_event_early' return.
