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.
