The commedi_async 'cur_chan' member is used to track the current position in the chanlist for a scan. Currently only a couple comedi drivers use this member. For aeshtetics, move the 'cur_chan' tracking into the core for non-SDF_PACKED subdevices. The 'cur_chan' will be updated after reading or writing samples to the async buffer by comedi_inc_scan_progress(). All non-SDF_PACKED subdevices will then automatiaclly track the 'cur_chan'. Some of the drivers use the 'cur_chan' to detect the end of scan event when counting scans. The COMEDI_CB_EOS event is automatically added by the core when the end of scan is detected. The drivers just need to check if the 'cur_chan' is 0 to count the number of scans completed.
