When setting up the DMA for 'read' streaming acquisition on the DIO subdevice, mark the whole buffer as writable before starting the DMA. This prevents a spurious detection of a DMA overwrite of good data during the first interrupt. Problem reported by Nicholas Nell. Fix suggested by Frank Mori Hess.
