iommu: Put domain allocation in __iommu_group_alloc_blocking_domain()

Browse source

There is no longer a reason to call __iommu_domain_alloc() to allocate
the blocking domain. All drivers that support a native blocking domain
provide it via the ops, for other drivers we should call
iommu_paging_domain_alloc().

__iommu_group_alloc_blocking_domain() is the only place that allocates
an BLOCKED domain, so move the ops->blocked_domain logic there.
