scftorture: Handle NULL argument passed to scf_add_to_free_list().
Dan reported that after the rework the newly introduced
scf_add_to_free_list() may get a NULL pointer passed. This replaced
kfree() which was fine with a NULL pointer but scf_add_to_free_list()
isn't.
Let scf_add_to_free_list() handle NULL pointer.
