[dh-cloud]

Description

when use Aligned timeseries, we found the Downsampling Aggregate Query has many null results

in function calcFromBatch(),curReadCurArrayIndex use the max curReadCurArrayIndex or batchData.getReadCurArrayIndex(), but not considered the curReadCurListIndex, curReadCurArrayIndex may less than (batchData.getReadCurListIndex() * capacity + batchData.getReadCurArrayIndex()), still use curReadCurArrayIndex, cause null value.
