Subject: [PATCH kernel] vfio-pci: Add missing break to enable VFIO_PCI_ERR_IRQ_INDEX

This adds a missing break statement to VFIO_DEVICE_SET_IRQS handler
without which vfio_pci_set_err_trigger() would never be called.

While we are here, add another "break" to VFIO_PCI_REQ_IRQ_INDEX case
so if we add more indexes later, we won't miss it.
