[media] media: vb2 dma-sg: Fully cache synchronise buffers in prepare and finish
In videobuf2 dma-sg memory types the prepare and finish ops, instead
of passing the number of entries in the original scatterlist as the
"nents" parameter to dma_sync_sg_for_device() and dma_sync_sg_for_cpu(),
the value returned by dma_map_sg() was used. Albeit this has been
suggested in comments of some implementations (which have since been
corrected), this is wrong.
Fixes: d790b7eda953 ("vb2-dma-sg: move dma_(un)map_sg here")
