[Xen-devel] [PATCH][ioemu and ioemu-remote]: fix multiple pci-attach/pci-detach by removing the meaningless irq_index

For HVM guest, we can't do pci-attach/pci-detach for >64 times due to
the meaningless checking in pci_register_device(). The attached patches
remove it.
With the patches, I made a test of 300 times of attach/detach and
everything works well.

fix_mulitple_hotplug.patch is for the old ioemu.
fix_mulitple_hotplug-for_ioemu-remote.patch is for the ioemu-remote.
They have a tiny difference about the header. So please apply them
