Robin Murphy 392bf51946 iommu: Make sysfs robust for non-API groups ... Groups created by VFIO backends outside the core IOMMU API should never be passed directly into the API itself, however they still expose their standard sysfs attributes, so we can still stumble across them that way. Take care to consider those cases before jumping into our normal assumptions of a fully-initialised core API group.
