Marek Szyprowski 5ec6148cb8 udmabuf: use sgtable-based scatterlist wrappers ...

commit afe3828437 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.
