Yan Zhao 7ef32e5236 vfio: add a singleton check for vfio_group_pin_pages ... Page pinning is used both to translate and pin device mappings for DMA purpose, as well as to indicate to the IOMMU backend to limit the dirty page scope to those pages that have been pinned, in the case of an IOMMU backed device. To support this, the vfio_pin_pages() interface limits itself to only singleton groups such that the IOMMU backend can consider dirty page scope only at the group level. Implement the same requirement for the vfio_group_pin_pages() interface.
