BE crash when trun on enable_filter_unused_columns_in_scan_stage

[wangruin]

Steps to reproduce the behavior (Required)

1. set enable_filter_unused_columns_in_scan_stage = true
2. admin set frontend config("enable_decimal_v3" = "false")
3. CREATE TABLE aggregate_table_with_null_v2 ( k1 char(20), k2 varchar(20), k3 date, k4 datetime, k5 boolean, v1 tinyint sum, v2 smallint sum, v3 int sum, v4 bigint max, v5 largeint max, v6 float min, v7 double min, v8 decimal(27,9) sum ) ENGINE=OLAP AGGREGATE KEY(k1, k2, k3, k4, k5) COMMENT "OLAP" DISTRIBUTED BY HASH(k1, k2) BUCKETS 3 PROPERTIES ( "replication_num" = "1", "storage_format" = "v2" );
4. insert some data
5. select sum(cast(v1 as int)), sum(v2), sum(v3), max(v4), max(v5), min(v6), min(v7), sum(v8) from aggregate_table_with_null_v2 where k3 = '2020-06-23' and k4 <= '2020-06-23 18:11:00';
6. the query returns 1 row when turn off enable_filter_unused_columns_in_scan_stage

Expected behavior (Required)
