perf evsel: Do not call pevent_free_format when deleting tracepoint

The libtraceevent library's main handle 'struct pevent' holds pointers
of every event that was added to it via functions:

  pevent_parse_format
  pevent_parse_event

We can't release struct event_format (call pevent_free_format)
separately, because that breaks that pointers array mentioned above and
another add_event call could end up with segfault.

All added events are released within the handle cleanup in pevent_free.
