Rob Bradford 363b478040 pci: vfio: Don't assume MSI-X is enabled ...

The fixup_msix_region() function added in
https://github.com/cloud-hypervisor/cloud-hypervisor/commit/a7187168310fec637a4cacd85674ed6d58336e0e
made the assumption that MSI-X was always available. This is the case
with many VFIO devices and all our virtio devices but created regression
with MSI devices.

Simply return the existing region size if MSI-X is not supported by the
device.

Fixes: #5649
