vb_calibinfo_get_data_bit_len

 return length of data bit from calib_info

 [usage]
   [len] = vb_calibinfo_get_data_bit_len(calib_info)

 [input]
   calib_info : <required> <<struct>> calibration information
              :  temporary struct for pre-process
              :   (new format 2011)

 [output]
