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.
