iommu/vt-d: Avoid duplicate device_domain_info structures
When a 'struct device_domain_info' is created as an alias for another device, this struct will not be re-used when the real device is encountered. Fix that to avoid duplicate device_domain_info structures being added. Signed-off-by: Joerg Roedel <jroedel@suse.de>
