Going directly to the storage engine is cheaper then going through the query engine. It avoids the overhead of allocating/deallocating the QE stages and walking the associated extra code.
StorageInterfaceImpl::findOplogEntryLessThanOrEqualToTimestamp is called as part of writing replication changes. Changing it to use the storage engine api will reduce the instruction count
Note: I have not measured the perf of this change alone
