Leon Romanovsky 61ceaf2361 vfio: Prevent from pinned DMABUF importers to attach to VFIO DMABUF 
Some pinned importers, such as non-ODP RDMA ones, cannot invalidate their
mappings and therefore must be prevented from attaching to this exporter.

Fixes: 5d74781ebc ("vfio/pci: Add dma-buf export support for MMIO regions")
