Siying Dong 9b51af5a17 [RocksDB Performance Branch] DBImpl.NewInternalIterator() to reduce works inside mutex 
Summary: To reduce mutex contention caused by DBImpl.NewInternalIterator(), in this function, move all the iteration creation works out of mutex, only leaving object ref and get.

Test Plan:
make all check
will run db_stress for a while too to make sure no problem.
