Summary: Fixes a bug introduced by me in https://github.com/facebook/rocksdb/pull/9733 That PR added a counter so that the per-thread seeds in ThreadState would be unique even when --benchmarks had more than one test. But it incorrectly used this counter as the value for ThreadState::tid as well. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9757 Test Plan: Confirm that unexpectedly good QPS results on the regression tests return to normal with this fix. I have confirmed that the QPS increase starts with the PR 9733 diff.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
