[PATCH v2] io: accel: kxcjk1013: restore the range after resume.

[Chen, Hu]

From: "he, bo" <bo.he@xxxxxxxxx>

On some laptops, kxcjk1013 is powered off when system enters S3. We need
restore the range regiter during resume. Otherwise, the sensor doesn't
work properly after S3.

Changes in v2:
- Handle return value independently in resume callback.
