[ Upstream commit 0776d1231bec0c7ab43baf440a3f5ef5f49dd795 ]
Reset the member "test_fs" of the test configuration after a call of the
function "kfree_const" to a null pointer so that a double memory release
will not be performed.
Fixes: d9c6a72d6fa2 ("kmod: add test driver to stress test the module loader")
