This PR try to resolved the `inner hits node is not an array` because when a
query( batch-size) run against new segment without this field, as-well the
filter_path just only take `hits.hits.fields` 、`hits.hits._source` into
account, this would appear an null inner hits node:
```
{
"_scroll_id": "DXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAHaUWY1ExUVd0ZWlRY2",
"hits": {
"total": 1
}
}
```

Unfortunately this PR introduce another serious inconsistent result with
different batch_size because of misusing the `total`.
To avoid this two problem, we just add `hits.hits._score` to filter_path
when `docvalue_mode` is true, `_score` would always `null` , and populate
the inner hits node:
```
{
"_scroll_id": "DXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAHaUWY1ExUVd0ZWlRY2",
"hits": {
"total": 1,
"hits": [
{
"_score": null
}
]
}
}
```
