[PATCH v2 1/7] async_tx: use dmaengine_desc_set_callback()

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

Replace open-coded assignments to callback and callback_param fields
of struct dma_async_tx_descriptor with calls to the
dmaengine_desc_set_callback() helper.

No functional change intended.
