linux-aio: implement io plug, unplug and flush io queue
This patch implements .bdrv_io_plug, .bdrv_io_unplug and
.bdrv_flush_io_queue callbacks for linux-aio Block Drivers,
so that submitting I/O as a batch can be supported on linux-aio.
[Unprocessed requests are completed with -EIO instead of a bogus ret
value.
