[SPARK-6554] [SQL] Don't push down predicates which reference partition
column(s)
There are two cases for the new Parquet data source:
1. Partition columns exist in the Parquet data files
We don't need to push-down these predicates since partition pruning
already handles them.
1. Partition columns don't exist in the Parquet data files
We can't push-down these predicates since they are considered as
invalide columns by Parquet.
