Eli Cohen 710eb8e32d vdpa/mlx5: Fix memory key MTT population ... map_direct_mr() assumed that the number of scatter/gather entries returned by dma_map_sg_attrs() was equal to the number of segments in the sgl list. This led to wrong population of the mkey object. Fix this by properly referring to the returned value. The hardware expects each MTT entry to contain the DMA address of a contiguous block of memory of size (1 << mr->log_size) bytes. dma_map_sg_attrs() can coalesce several sg entries into a single scatter/gather entry of contiguous DMA range so we need to scan the list and refer to the size of each s/g entry. In addition, get rid of fill_sg() which effect is overwritten by populate_mtts().
