vfio/mdev: Uses the vfio emulated iommufd ops set in the mdev sample drivers
This harmonizes the no-DMA devices (the vfio-mdev sample drivers) with
the emulated devices (gvt-g, vfio-ap etc.). It makes it easier to add
BIND_IOMMUFD user interface which requires to return an iommufd ID to
represent the device/iommufd bond.
