perf trace: Add missed freeing of ordered events and thread

description
===========
Caught by leak sanitizer running "perf trace BTF general tests". Make
the ordered_events initialization unconditional and early so that
trace__exit cleanup is simple - ordered_events__init doesn't allocate
and just sets up 4 values and inits 3 list heads.
