Expected behavior

---

//{conn-10006, pstmt-20499, rs-51029} closed
{conn-10006, pstmt-20499, rs-51028} closed
//{conn-10006, pstmt-20500, rs-51031} closed
{conn-10006, pstmt-20500, rs-51030} closed

Actual behavior

{conn-10006, pstmt-20499, rs-51029} closed
{conn-10006, pstmt-20499, rs-51028} closed
{conn-10006, pstmt-20500, rs-51031} closed

Reason analyze (If you can)

private List<ResultSet> getResultSets() throws SQLException {
        List<ResultSet> result = new ArrayList<>(statements.size());
        for (Statement each : statements) {
            if (null != each.getResultSet()) {
                result.add(each.getResultSet());
            }
        }
        return result;
    }

each.getResultSet(), this codes would make a new instanceof resultSet，so the com.alibaba.druid.filter.Filter#resultSet_close will be called twice. com.alibaba.druid.filter.stat.StatFilterContext#addFetchRowCount,this rowCount added twice, is fault.

Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.

Example codes for reproduce this issue (such as a github link).
