[SPARK-14774][SQL] Write unscaled values in ColumnVector.putDecimal
## What changes were proposed in this pull request?
We recently made `ColumnarBatch.row` mutable and added a new
`ColumnVector.putDecimal` method to support putting `Decimal` values in the
`ColumnarBatch`. This unfortunately introduced a bug wherein we were not
updating the vector with the proper unscaled values.
## How was this patch tested?
This codepath is hit only when the vectorized aggregate hashmap is enabled.
https://github.com/apache/spark/pull/12440 makes sure that a number of
regression tests/benchmarks test this bugfix.
