Currently error messages when the security counter updates fail (i.e. when Rollback protection is enabled) just return a textual string and possibly the image ID failing. Amend that such that it will also return the error code
rcfrom the platform functions that are accessing the security counter, as it helps debugging where the issue might lie without providing a special build with logging enabled or attaching to the device which might be impractical.
