[PATCH] perf script: Fix error handling path

From: Christophe JAILLET
Date: Sat Sep 16 2017 - 02:29:12 EST


If the string passed in '--time' is invalid, or if failed to set
libtraceevent function resolver, we must do some cleanup before leaving.
As in the other error handling paths of this function.
