[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?
