The iommu drivers are on the way to drop the remove_dev_pasid op by
extending the blocked_domain to support PASID. However, this cannot be
done in one shot. So far, the Intel iommu and the ARM SMMUv3 driver have
supported it, while the AMD iommu driver has not yet. During this
transition, the IOMMU core needs to support both ways to destroy the
attachment of device/PASID and domain.

This patch should be moved before the change in drivers. After all
drivers convert to use set blocking domain to pasid, the
remove_dev_pasid could be removed as the last step.
you are right! let me fix it.
