staging: comedi: amplc_dio200_common: use comedi_cmd pointer

Browse source

Use the local variable to access the comedi_cmd as a pointer
in dio200_read_scan_intr() instead of getting to it from the
comedi_subdevice pointer.

Remove the unnecessary local variable 'len', this is just the
cmd->chanlist_len.
