iommu/ipmmu-vmsa: Update to {map,unmap}_pages
Update map/unmap to the new multi-page interfaces, which is dead easy
since we just pass them through to io-pgtable anyway. Since these are
domain ops now, the domain is inherently valid (not to mention that
container_of() wouldn't return NULL anyway), so garbage-collect that
check in the process.
