perf trace: Free malloc'd trace fields on exit
ASan reports several memory leaks running:
# perf test "88: Check open filename arg using perf trace + vfs_getname"
The first of these leaks is related to struct trace fields never being
deallocated.
This patch adds the function trace__exit, which is called at the end of
cmd_trace, replacing the existing deallocation, which is now moved
inside the new function.
This function deallocates:
- ev_qualifier
- ev_qualifier_ids.entries
- syscalls.table
- sctbl
- perfconfig_events
