coresight: perf: Release Coresight path when alloc trace id failed

Browse Source 
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")
