Delete meaningless err check

**What this PR does / why we need it**:
Delete meaningless err check
We don't need to care about err check. In cited function, if err is not nil, I return t.Errorf directly.
So it does not matter that whether data is nil or err is nil.

**Release note**:

```release-note\
