    xen/x86: shadow: The return type of sh_audit_flags() should be const
    
    The function sh_audit_flags() is returning pointer to literal strings.
    They should not be modified, so the return is now const and this is
    propagated to the callers.
    
    Take the opportunity to fix the coding style in the declaration of
    sh_audit_flags.
