PCI: Drop "irq" param from *_restore_msi_irqs()
Change x86_msi.restore_msi_irqs(struct pci_dev *dev, int irq) to
x86_msi.restore_msi_irqs(struct pci_dev *dev).
restore_msi_irqs() restores multiple MSI-X IRQs, so param 'int irq' is
unneeded. This makes code more consistent between vm and bare metal.
Dom0 MSI-X restore code can also be optimized as XEN only has a hypercall
to restore all MSI-X vectors at one time.
