media: omap3isp: use sgtable-based scatterlist wrappers

commit 3de572fe2189a4a0bd80295e1f478401e739498e upstream.

Use common wrappers operating directly on the struct sg_table objects to
fix incorrect use of scatterlists sync calls. dma_sync_sg_for_*()
functions have to be called with the number of elements originally passed
to dma_map_sg_*() function, not the one returned in sgtable's nents.
