[SPARK-23415][SQL][TEST] Make behavior of BufferHolderSparkSubmitSuite correct and stable ## What changes were proposed in this pull request? This PR addresses two issues in `BufferHolderSparkSubmitSuite`. 1. While `BufferHolderSparkSubmitSuite` tried to allocate a large object several times, it actually allocated an object once and reused the object. 2. `BufferHolderSparkSubmitSuite` may fail due to timeout To assign a small object before allocating a large object each time solved issue 1 by avoiding reuse. To increasing heap size from 4g to 7g **probably** solved issue 2. It can also avoid OOM after fixing issue 1. ## How was this patch tested?
