    xen/param: address violations of MISRA C Rule 20.7
    
    MISRA C Rule 20.7 states: "Expressions resulting from the expansion
    of macro parameters shall be enclosed in parentheses". Therefore, some
    macro definitions should gain additional parentheses to ensure that all
    current and future users will be safe with respect to expansions that
    can possibly alter the semantics of the passed-in macro parameter.
    
    No functional change.
