vfio/pci: Pass an error object to vfio_populate_vga
Pass an error object to prepare for the same operation in
vfio_populate_device. Eventually this contributes to the migration
to VFIO-PCI realize.
We now report an error on vfio_get_region_info failure.
vfio_probe_igd_bar4_quirk is not involved in the migration to realize
and simply calls error_reportf_err.
