[SPARK-15871][SQL] Add `assertNotPartitioned` check in `DataFrameWriter`
## What changes were proposed in this pull request?
Sometimes it doesn't make sense to specify partitioning parameters, e.g.
when we write data out from Datasets/DataFrames into `jdbc` tables or streaming
`ForeachWriter`s.
This patch adds `assertNotPartitioned` check in `DataFrameWriter`.
## How was this patch tested?
New dedicated tests.
