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.
