====================
net: microchip: sparx5: Fix some memory leaks in vcap_api_kunit

There are some memory leaks in vcap_api_kunit, this patchset
fixes them.

Changes in v3:
- Fix the typo in patch 3, from "export" to "vcap enabled port".
- Fix the typo in patch 4, from "vcap_dup_rule" to "vcap_alloc_rule".

Changes in v2:
- Adhere to the 80 character limit in vcap_free_caf()
- Fix kernel test robot reported warnings in test_vcap_xn_rule_creator()
====================
