x86, AMD IOMMU: initialize dma_ops after sysfs registration
If sysfs registration fails all memory used by IOMMU is freed. This happens after dma_ops initialization and the functions will access the freed memory then. Fix this by initializing dma_ops after the sysfs registration. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
