Joerg Roedel b548e786ce iommu/amd: Init unity mappings only for dma_ops domains
The default domain for a device might also be
identity-mapped. In this case the kernel would crash when
unity mappings are defined for the device. Fix that by
making sure the domain is a dma_ops domain.

Fixes: 0bb6e243d7 ('iommu/amd: Support IOMMU_DOMAIN_DMA type allocation')
