IMPALA-4285: Fix Parquet scanner with MT_DOP > 0 and no materialized slots.
The problem was that there was a reference to HdfsScanner::batch_
hidden inside WriteEmptyTuples(). The batch_ reference is NULL when the
scanner is run in MT mode (i.e. with MT_DOP > 1).
Testing: Added a new test_mt_dop.py test.
