[0/2] tracing: Clean up how iter is freed

Message

The trace iterator is used in various interfaces and needs to be consistent
in how it is cleaned up. Add a helper function to clean up its content. But
before doing so, I noticed that iter->trace is allocated then the content
of tr->current_trace is copied to it. There's no reason for this, so the
first patch removes that allocation and just points to the content of
tr->current_trace, as tr->current_trace can change, but the content should
not.
