[PATCH 2/8] perf inject: Fill in the missing session freeing after an error occurs

[Arnaldo Carvalho de Melo <acme@kernel.org>]

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

When an error occur 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.
