[RFC,V3,17/26] vfio/pci: Make vfio_pci_set_irqs_ioctl() available

Commit Message

Reinette Chatre Oct. 27, 2023, 5 p.m. UTC

vfio_pci_set_irqs_ioctl() is now a generic entrypoint that can
be configured to support different interrupt management backend.

Export vfio_pci_set_irqs_ioctl() for use by other virtual device
drivers.
