[SPARK-16905] SQL DDL: MSCK REPAIR TABLE (follow-up)
## What changes were proposed in this pull request?
This PR split the the single `createPartitions()` call into smaller
batches, which could prevent Hive metastore from OOM (caused by millions of
partitions).
## How was this patch tested?
Will test this manually on millions of partitions.
