kxcjk1013: code cleanup and update sensor description

Browse Source 
Code cleanup and proper close iio device in destructor.

KXCJK-1013 is tri-axis accelerometer from Kionix.
This sensor can measure acceleration in metre per second squared or in
G-forces.

The library provided is libupm-kxcjk1013.so.0.4.0.
The example provided is kxcjk1013-example where it will print x,y,z axis when
trigger buffer data is ready.
