The return value of bogus_8259A_irq() is wrong: the function will return `true` when the IRQ is real and `false` when it's a spurious IRQ. This causes the "No irq handler for vector ..." message in do_IRQ() to be printed for spurious i8259 interrupts which is not intended (and not helpful).
Fix by inverting the return value of bogus_8259A_irq().
