perf cs-etm: Fix thread leaks on trace queue init failure

Browse source

cs_etm__init_traceid_queue() allocates the frontend and decode threads,
if a later allocation fails, the error path does not drop thread
reference that was already acquired.

Release both thread pointers with thread__zput() on the error path, so
does not leak thread references or leave stale pointers behind.
