coresight: perf: Release Coresight path when alloc trace id failed
Error handler for etm_setup_aux can not release coresight path because
cpu mask was cleared when coresight_trace_id_get_cpu_id failed.
Call coresight_release_path function explicitly when alloc trace id filed.
Fixes: 4ff1fdb4125c4 ("coresight: perf: traceid: Add perf ID allocation and notifiers")
