[PATCH 4/4] Talitos: fix the issue of dma memory leak

[Qiang Liu]

An error will be happened when test with mass data:
"DMA-API: device driver tries to sync DMA memory it has not allocated";
"DMA-API: debugging out of memory - disabling"
dma mapping memory of request->desc is not released by right device,
it should be private->dev but not dev;
