If domain attaching to device fails, the IOMMU driver should bring the device to blocking DMA state. The upper layer is expected to recover it by attaching a new domain. Use device_block_translation() in the error path of dev_attach to make the behavior specific. The difference between device_block_translation() and the previous dmar_remove_one_dev_info() is that, in the scalable mode, it is the RID2PASID entry instead of context entry being cleared. As a result, enabling PCI capabilities is moved up.
