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: Did not add a test since we don't have a good place to add
MT tests yet.
