From: Horia Geantă <horia.geanta@xxxxxxx> Modify drive to provide a valid errno (and not the HW error ID) to the user, via completion callbacks. A "valid errno" is currently not explicitly mentioned in the docs, however the error code is expected to match the one returned by the generic SW implementation. Note: in most error cases caam/qi and caam/qi2 returned -EIO; align all caam drivers to return -EINVAL. While here, ratelimit prints triggered by fuzz testing, such that console is not flooded.
