Haobo Xu c3c13db346 [RocksDB] [Performance Bug] MemTable::Get Slow ...

Summary:
The merge operator diff introduced a performance problem in MemTable::Get.
An exit condition is missed when the current key does not match the user key.
This could lead to full memtable scan if the user key is not found.

Test Plan: make check; db_bench
