Jay Zhuang fa92b9dc9f Fix TSAN build and re-enable the tests (#7386) 
Summary:
Resolve TSAN build warnings and re-enable disabled TSAN tests.

Not sure if it's a compiler issue or TSAN check issue. Switching from
conditional operator to if-else mitigated the problem.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7386

Test Plan:
run TSAN check 10 times in circleci.
