[SPARK-13747][SQL]Fix concurrent executions in ForkJoinPool for SQL ## What changes were proposed in this pull request? Calling `Await.result` will allow other tasks to be run on the same thread when using ForkJoinPool. However, SQL uses a `ThreadLocal` execution id to trace Spark jobs launched by a query, which doesn't work perfectly in ForkJoinPool. This PR just uses `Awaitable.result` instead to prevent ForkJoinPool from running other tasks in the current waiting thread. ## How was this patch tested?
