[PATCH 20/20] perf util/probe-file: delete namelist on error in del_events

ASan reports some memory leaks when running the perf test
"42: BPF filter".
This second leak is caused by a strlist not being dellocated on error
inside probe_file__del_events.

This patch adds a goto label before the deallocation and makes the error
path jump to it.
