[SPARK-12898] Consider having dummyCallSite for HiveTableScan
Currently, HiveTableScan runs with getCallSite which is really expensive and shows up when scanning through large table with partitions (e.g TPC-DS) which slows down the overall runtime of the job. It would be good to consider having dummyCallSite in HiveTableScan.

Closes #10825 from rajeshbalamohan/SPARK-12898.
