[RFC,v3,5/5] block/nvme: Use qemu_vfio_pci_init_msix_irqs() to initialize our IRQ

Commit Message

Philippe Mathieu-Daudé Aug. 18, 2020, 4:45 p.m. UTC

Instead of initializing one MSIX IRQ with the generic
qemu_vfio_pci_init_irq() function, use the MSIX specific one which
will allow us to use multiple IRQs. For now we provide an array of
a single IRQ.
