    public: misra rule 20.7 fix on errno.h
    
    Cppcheck has found a violation of rule 20.7 for the macro XEN_ERRNO,
    while the macro parameter is never used as an expression, it doesn't
    harm the code or the readability to add parenthesis, so add them.
    
    This finding is reported also by eclair and coverity.
