Subject: [PATCH v2 1/2] perf cs-etm: Remove errnoeous ERR_PTR() usage in cs_etm__process_auxtrace_info

From: YueHaibing <yuehaibing@...wei.com>

intlist__findnew() doesn't uses ERR_PTR() as a return mechanism
so its callers shouldn't try to extract the error using PTR_ERR(
ret) from intlist__findnew(), make cs_etm__process_auxtrace_info
return -ENOMEM instead.

Fixes: cd8bfd8c973e ("perf tools: Add processing of coresight metadata")
