[RESEND][PATCH v19 16/26] vhost: remove group-related API from driver

[David Marchand <david.marchand@redhat.com>]

From: Anatoly Burakov <anatoly.burakov@intel.com>

The vDPA driver API has "get_vfio_group_fd" in its ops structure, but no
driver is using it any more, as better API's were added and implemented.
Remove this API from vDPA ops structure.
