Sorry, rereading the code I see that that's not quite right.
bdrv_aio_* routines return NULL to indicate that the callback has
already been done; any error is given to the callback to handle.
That's what this one should do; that part code should look quite like
the innards of bdrv_aio_read_em.

Ian.
