vdpa/mlx5: Use vq suspend/resume during .set_map
Instead of tearing down and setting up vq resources, use vq suspend/resume during .set_map to speed things up a bit. The vq mr is updated with the new mapping while the vqs are suspended. If the device doesn't support resumable vqs, do the old teardown and setup dance.
