[PATCH v3 02/21] iommufd: Use iommu_paging_domain_alloc()

If the iommu driver doesn't implement its domain_alloc_user callback,
iommufd_hwpt_paging_alloc() rolls back to allocate an iommu paging domain.
Replace iommu_domain_alloc() with iommu_user_domain_alloc() to pass the
device pointer along the path.
