[SPARK-21871][SQL] Fix infinite loop when bytecode size is larger than spark.sql.codegen.hugeMethodLimit ## What changes were proposed in this pull request? When exceeding `spark.sql.codegen.hugeMethodLimit`, the runtime fallbacks to the Volcano iterator solution. This could cause an infinite loop when `FileSourceScanExec` can use the columnar batch to read the data. This PR is to fix the issue. ## How was this patch tested?
