[SPARK-15871][SQL] Add `assertNotPartitioned` check in `DataFrameWriter`

## What changes were proposed in this pull request?

It doesn't make sense to specify partitioning parameters, when we write data out from Datasets/DataFrames into `jdbc` tables or streaming `ForeachWriter`s.

This patch adds `assertNotPartitioned` check in `DataFrameWriter`.
