ARM: 8818/1: dma-mapping: update comment about handling dma_ops when detaching from IOMMU
Update the comment because we don't set the pointer to NULL anymore.
Also use the correct pointer name 'dma_ops' instead of 'dma_map_ops'.
Fixes: 1874619a7df4 ("ARM: dma-mapping: Set proper DMA ops in arm_iommu_detach_device()")
