The reason is that some PCI devices may have no PCI interrupt, though they may have interrupts attached via other means. In this case, we shall not use irq->pdev, but device-specific code can later retreive those interrupts instead. Without that patch, Maple and derivatives don't get the right interrupt for the second IDE channel as the linux IDE code fallsback to the PCI irq instead of trying to use the legacy ones for the on-board controller (which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it doesn't request any) fixes it.
