Jonathan Marek 62b5e322fb drm/msm: use for_each_sgtable_sg to iterate over scatterlist
The dma_map_sgtable() call (used to invalidate cache) overwrites sgt->nents
with 1, so msm_iommu_pagetable_map maps only the first physical segment.

To fix this problem use for_each_sgtable_sg(), which uses orig_nents.

Fixes: b145c6e65e ("drm/msm: Add support to create a local pagetable")
