staging: comedi: cb_pcidas: use comedi_async 'scans_done' to detect AO EOA

Remove the private data member 'ao_count' and use the comedi_async 'scans_done'
member to detect the analog output end-of-acquisition.

Use the comedi_nsamples_left() helper to get the number of samples to actually
read from the async buffer.
