Subject[PATCH] lib/test_kmod: Potential double free in error handling
There is a copy and paste bug so we set "config->test_driver" to NULL
twice instead of setting "config->test_fs". Smatch complains that it
leads to a double free:

lib/test_kmod.c:840 __kmod_config_init() warn: 'config->test_fs' double freed

Fixes: d9c6a72d6fa2 ("kmod: add test driver to stress test the module loader")
