[PATCH] AMD IOMMU: initialize dma_ops after sysfs registration

[Joerg Roedel]

This patch moves the initialization of the dma_ops interface for AMD IOMMU
behind the sysfs registration. Without this and if sysfs registration fails the
AMD IOMMU driver is still in place and operates on already freed data.
