iommu/amd: Remove the unnecessary assignment
The assignment of the global variable 'iommu_detected' has been moved from amd_iommu_init_dma_ops() to amd_iommu_detect(), so this patch removes the assignment in amd_iommu_init_dma_ops(). Signed-off-by: Adrian Huang <ahuang12@lenovo.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
