staging: comedi: aio_aio12_8: use comedi_subdevice 'readback'
Use the new comedi_subdevice 'readback' member and the core provided
(*insn_read) for the readback of the analog output subdevice channels.
Remove the unused private data and its allocation.
For aesthetics, rename the (*insn_write) function and tidy it up.
