Lu Baolu 2b989ab9bc iommu/vt-d: Add helper to allocate paging domain
The domain_alloc_user operation is currently implemented by allocating a
paging domain using iommu_domain_alloc(). This is because it needs to fully
initialize the domain before return. Add a helper to do this to avoid using
iommu_domain_alloc().
