aliguori 7403b14eeb Fix DMA API when handling an immediate error from block layer (Avi Kivity)

The block layer may signal an immediate error on an asynchronous request
by returning NULL.  The DMA API did not handle this correctly, returning
an AIO request which would never complete (and which would crash if
cancelled).

Fix by detecting the failure and propagating it.
