staging: comedi: ni_mio_common: fix interrupt handler for dev->write_subdev
There may not be a dev->write_subdev, i.e. an analog output subdevice, that
supports async commands. If it doesn't exist the interrupt/dma will never
be enabled. Fix ni_E_interrupt() so that the analog output subdevice is
only handled if it exists.
