ide: Fix ide_dma_cancel
When cancelling a request, bdrv_aio_cancel may decide that it waits for completion of a request rather than for cancellation. IDE therefore can't abandon its DMA status before calling bdrv_aio_cancel; otherwise the callback of a completed request would use invalid data. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
