[SPARK-5862][SQL] Only transformUp the given plan once in
HiveMetastoreCatalog
Current `ParquetConversions` in `HiveMetastoreCatalog` will transformUp the
given plan multiple times if there are many Metastore Parquet tables. Since the
transformUp operation is recursive, it should be better to only perform it once.
