Subject: [PATCH 4/8] perf report: Fill in the missing session freeing after an error occurs

From: Taeung Song <treeze.taeung@...il.com>

When an error occurs an error value is just returned without freeing the
session. So allocating and freeing session have to be matched as a pair
even if an error occurs.
