iio: accel: kxcjk-1013: Fix kxcjk10013_set_range

Currently, we get the new GSEL bits by OR-ing the old values
with the new ones. This only works first time when the old
values are 0.

Startup:
	* GSEL0 = 0, GSEL1 = 0

Set range to 4G: (GSEL0 = 1, GSEL1 = 0)
	* GSEL0 = 0 | 1 = 1
	* GSEL1 = 0 | 0 = 0
	* correct

Change range to 2G: (GSEL0 = 0, GSEL1 = 0)
	* GSEL0 = 1 | 0 = 1
	* GSEL1 = 0 | 0 = 0
	* wrong, GSEL0 should be 0

This has the nice effect that we can use the full scale range,
exported in in_accel_scale_available.
