dma: use current AioContext for dma_blk_io()

Browse source 
In the past a single AioContext was used for block I/O and it was
fetched using blk_get_aio_context(). Nowadays the block layer supports
running I/O from any AioContext and multiple AioContexts at the same
time. Remove the dma_blk_io() AioContext argument and use the current
AioContext instead.

This makes calling the function easier and enables multiple IOThreads to
use dma_blk_io() concurrently for the same block device.
