iommu/s390: Tolerate repeat attach_dev calls
Since commit 0286300e6045 ("iommu: iommu_group_claim_dma_owner() must
always assign a domain") s390-iommu will get called to allocate multiple
unmanaged iommu domains for a vfio-pci device -- however the current
s390-iommu logic tolerates only one. Recognize that multiple domains can
be allocated and handle switching between DMA or different iommu domain
tables during attach_dev.
