[SPARK-19152][SQL][FOLLOWUP] simplify CreateHiveTableAsSelectCommand
## What changes were proposed in this pull request?
After https://github.com/apache/spark/pull/16552 , `CreateHiveTableAsSelectCommand` becomes very similar to `CreateDataSourceTableAsSelectCommand`, and we can further simplify it by only creating table in the table-not-exist branch.
This PR also adds hive provider checking in DataStream reader/writer, which is missed in #16552
## How was this patch tested?
N/A
Author: Wenchen Fan <wenchen@databricks.com>
Closes #16693 from cloud-fan/minor.
