Streamline cleanup logic in MAC finish

Reorganize error handling code in psa_mac_finish_internal,
psa_mac_sign_finish and psa_mac_verify finish to ensure that:

* psa_mac_abort() is always called, on all success and error paths.
* psa_mac_finish places a safe value in the output parameters on
  all error paths, even if abort fails.
