iommu/amd: Fix crash when accessing AMD-Vi sysfs entries
The link between the iommu sysfs-device and the struct amd_iommu is no longer stored as driver-data. Update the code to the new correct way of getting from device to amd_iommu. Reported-by: Dave Jones <davej@codemonkey.org.uk> Fixes: 39ab9555c241 ('iommu: Add sysfs bindings for struct iommu_device') Signed-off-by: Joerg Roedel <jroedel@suse.de>
