perf cs-etm: Don't add global v0 HW_IDs to unformatted queues
In the case of mixed formatted and unformatted trace with v0 HW_IDs, or no HW_IDs at all resulting in the cs_etm__map_trace_ids_metadata() fallback, formatted queues will write their HW_IDs to unformatted queues. This will result in an assert because of multiple decoders on an unformatted queue. Fix it by not inserting trace ID nodes on other unformatted queues. This isn't an issue for v0.1 HW_IDs because they aren't global so will only add to their own queue.
