[SPARK-8841] [SQL] Fix partition pruning percentage log message
When pruning partitions for a query plan, a message is logged indicating what how many partitions were selected based on predicate criteria, and what percent were pruned.
The current release erroneously uses `1 - total/selected` to compute this quantity, leading to nonsense messages like "pruned -1000% partitions". The fix is simple and obvious.

Closes #7227 from srlindemann/master and squashes the following commits:
