[PATCH v2 3/3] media: pxa_camera: use cookie returned by dmaengine_submit() for logging

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

The debug print in pxa_dma_add_tail_buf() was logging buf->descs[i]->cookie
instead of buf->cookie[i].

dmaengine_submit() returns the cookie and it is stored in buf->cookie[i],
so use that value in the dev_dbg() call to accurately reflect the submitted
cookie.

Prepare to make struct dma_async_tx_descriptor private to the DMA engine.
