Daniel Bristot de Oliveira 5e8446e382 tracing: Dump stacktrace trigger to the corresponding instance ...

commit ce33c845b0 upstream.

The stacktrace event trigger is not dumping the stacktrace to the instance
where it was enabled, but to the global "instance."

Use the private_data, pointing to the trigger file, to figure out the
corresponding trace instance, and use it in the trigger action, like
snapshot_trigger does.
