Tiezhu Yang 8620d18575 test_kmod: avoid potential double free in trigger_config_run_type() 
[ Upstream commit 0776d1231b ]

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: d9c6a72d6f ("kmod: add test driver to stress test the module loader")
