Summary: **Context/Summary:** We discovered the following false positive in our crash test lately: (1) PUT() writes k/v to WAL but fails in `ApplyWALToManifest()`. The k/v is in the WAL (2) Current stress test logic will rollback the expected state of such k/v since PUT() fails (3) If the DB crashes before recovery finishes and reopens, the WAL will be replayed and the k/v is in the DB while the expected state have been roll-backed. We decided to leave those expected state to be pending until the loop-write of the same key succeeds. Bonus: Now that I realized write to manifest can also fail the write which faces the similar problem as https://github.com/facebook/rocksdb/pull/12797, I decided to disable fault injection on user write per thread (instead of globally) when tracing is needed for prefix recovery; some refactory Pull Request resolved: https://github.com/facebook/rocksdb/pull/12838 Test Plan: Rehearsal CI Run below command (varies on sync_fault_injection=1,0 to verify ExpectedState behavior) for a while to ensure crash recovery validation works fine ``` python3 tools/db_crashtest.py --simple blackbox
