configrom: there is no obvious reason why a space should be added to the end of the vendor and model strings returned from the interface.  Retain the explicit null termination of these strings to cover for the case where an interface may not return any null bytes.  Also fix indentation associated with the null termination code.  The issue with the trailing space was noticed and reported by Nils Philippsen: its presence broke a test in the saffire_dice mixer python code.
