net: microchip: sparx5: Fix possible memory leaks in test_vcap_xn_rule_creator()
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.
