Subject: [PATCH 5/5] test_kmod: fix small memory leak on filesystem tests

From: Dan Carpenter <dan.carpenter@...cle.com>

The break was in the wrong place so file system tests don't work as
intended, leaking memory at each test switch.

Fixes: 39258f448d71 ("kmod: add test driver to stress test the module loader")
