x86/pci: update pirq_enable_irq() to setup io apic routing
So we can set io apic routing only when enabling the device irq. This is advantageous for IRQ descriptor allocation affinity: if we set up the IO-APIC entry later, we have a chance to allocate the IRQ descriptor later and know which device it is on and can set affinity accordingly.
