dataplane: fix hang introduced by AioContext transition
The bug is that the EventNotifiers do have a NULL io_flush callback.
Because _none_ of the callbacks on the dataplane AioContext have such a
callback, aio_poll will simply do nothing. Fixed by adding the callbacks:
the ioeventfd will always be polled (this can change in the future to
pause/resume the processing during live snapshots or similar operations);
the ioqueue will be polled if there are outstanding requests.
I must admit I have screwed up my testing somehow, because commit
2c20e71 does not work even if cherry-picked on top of 1.4.0, and this
patch fixes it there as well.
