staging: comedi: usbdux: clarify bipolar ai data in usbduxsub_ai_isoc_irq()

Use the comedi_range_is_bipolar() helper instead of checking the
'range' index against a magic number.

Also, use the s->maxdata to calculate the value needed to munge the
value for bipolar data instead of the magic number.
