    xen/arm: initialize access
    
    Initialize variable *access before returning it back to the caller.
    It makes the code a bit nicer and it is a safety certification
    requirement.
    
    M3CM Rule-9.1: The value of an object with automatic storage duration
    shall not be read before it has been set
