[SPARK-8202] [PYSPARK] fix infinite loop during external sort in PySpark
The batch size during external sort will grow up to max 10000, then shrink
down to zero, causing infinite loop.
Given the assumption that the items usually have similar size, so we don't
need to adjust the batch size after first spill.
