staging: comedi: cb_das16_cs: remove unneeded default case in analog in read 

The default (return -EINVAL) case is not needed when working
out the correct value to set the analog input range. As pointed
out by Ian Abbott, the comedi core checks the range in
comedi_check_chanlist() before calling the insn_read() function.
