ide: Reset BMIDEA bit when the bus master is stopped
The device is supposed to reset the Bus Master IDE Active bit in the status register when 0 is written to the Start/Stop Bus Master bit in the command register. In the common cases this happens automatically because bdrv_drain_all() flushes the requests, but with a large PRDT it could remain set. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
