New requirement for the vfio drivers was added by the commit

followed by commit 1b0ecb5baf4a ("vfio/pci: Convert all PCI drivers
to get_region_info_caps") that was missed by the new vfio/xe driver.
Add handler for .get_region_info_caps to avoid -EINVAL errors.
Fixes: 2e38c50ae492 ("vfio/xe: Add device specific vfio_pci driver variant for Intel
graphics")

I tested it on v6.19-rc1 with QEMU 8.2.2
passing through an Intel Xe VF. The patch fixes the -EINVAL failure
on VFIO_DEVICE_GET_REGION_INFO.
