Inject fault while probing kunit-example-test.ko, the duprule which is allocated by kzalloc in vcap_dup_rule(), the field which is allocated by kzalloc in vcap_rule_add_action() and vcap_rule_add_key() is not freed, and it cause the memory leaks below. Use vcap_free_rule() to free them as other drivers do it. And since the return rule of test_vcap_xn_rule_creator() is not used, remove it and switch to void. unreferenced object 0xffff058383334240 (size 192): comm "kunit_try_catch", pid 309, jiffies
