staging: comedi: das16: use comedi_async 'scans_done' to detect EOA
Refactor das16_interrupt() to use the comedi_async 'scans_done' member to
detect the End-of-Acquisition for the async command. Use the helper function
comedi_nsamples_left() to determine if DMA needs to be restarted.
This allows the removal of the private data 'adc_byte_count' and fixes a
possible integer overflow issue when that value is calculated.
