[PATCH 25/28] perf cs-etm: Remove errnoeous ERR_PTR() usage in cs_etm__process_auxtrace_info

[Arnaldo Carvalho de Melo]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

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.
