fix(bulk loader): Remove redundant option set (#6119)

The compression level is set in the `setBadgerOptions` function and setting
`compressionLevel` before calling that function is a no-op since we will
overwrite the value in the `setBadgerOptions` function.

This PR removes the redundant setting of the option.
