    x86/irq: parenthesize negative constants
    
    These constants are parenthesized to avoid them from
    possibly influencing the semantics of the constructs where it is used,
    especially inside macros invocations.
    
    This also resolves some violations of MISRA C Rule 20.7
    ("Expressions resulting from the expansion of macro parameters shall
    be enclosed in parentheses").
    
    No functional change.
