x86: IRQ Migration logic enhancement.

To programme MSI's addr/vector safely, delay irq migration
operation before acking next interrupt. In this way, it should
avoid inconsistent interrupts generation due to non-atomic writing
addr and data registers about MSI.

Port the logic from Linux and tailor it for Xen.
