Subject: test_kmod: fix small memory leak on filesystem tests
The break was in the wrong place so file system tests don't work as
intended, leaking memory at each test switch.
[mcgrof@kernel.org: massaged commit subject, noted memory leak issue without the fix]
Link: http://lkml.kernel.org/r/20170802211450.27928-6-mcgrof@kernel.org
Fixes: 39258f448d71 ("kmod: add test driver to stress test the module loader")
