This one fixes a race which qemu had also in iscsi block driver
between cancellation and io completition.

qemu_rbd_aio_cancel was not synchronously waiting for the end of
the command.

To archieve this it introduces a new status flag which uses
-EINPROGRESS.

-    qemu_aio_release(acb);
+    if (!acb->cancelled)

Missing braces, please read CODING_STYLE.

Will fix this if the rest is OK. Waiting for Stefan and Paolo.
