The vcap_decode_rule() never returns NULL. There is no need to check for that. This code assumes that if it did return NULL we should end abruptly and return success. It is confusing. Fix the check to just be if (IS_ERR()) instead of if (IS_ERR_OR_NULL()).

Inject fault while probing kunit-example-test.ko, the duprule which
is allocated by kzalloc in vcap_dup_rule() of
test_vcap_xn_rule_creator() is not freed, and it cause the memory leaks
below. Use vcap_del_rule() to free them as other functions do it.

Inject fault while probing kunit-example-test.ko, the rule which
is allocated by kzalloc in vcap_alloc_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.

Inject fault while probing kunit-example-test.ko, the duprule which
is allocated in vcap_dup_rule() and the vcap enabled port which
is allocated in vcap_enable() of vcap_enable_lookups in
vcap_api_encode_rule_test() is not freed, and it cause the memory
leaks below.
Use vcap_enable_lookups() with false arg to free the vcap enabled
port as other drivers do it. And use vcap_del_rule() to
free the duprule.

Inject fault When select CONFIG_VCAP_KUNIT_TEST, the below memory leak
occurs. If kzalloc() for duprule succeeds, but the following
kmemdup() fails, the duprule, ckf and caf memory will be leaked. So kfree
them in the error path.
