staging: comedi: usbduxfast: use comedi_async 'scans_done' to detect AI EOA

Browse source

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

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