Shane Francis aeeda19db4 drm/radeon: fix scatter-gather mapping with user pages 
commit 47f7826c52 upstream.

Calls to dma_map_sg may return less segments / entries than requested
if they fall on page bounderies. The old implementation did not
support this use case.

Fixes: be62dbf554 ("iommu/amd: Convert AMD iommu driver to the dma-iommu api")
