Summary: crash-recovery verification is failing in the whitebox testing, which may or may not be a valid correctness issue -- need more time to investigate. In the meantime, reverting so we don't mask other failures. Closes https://github.com/facebook/rocksdb/pull/3786 Differential Revision: D7794516 Pulled By: ajkr fbshipit-source-id: 28ccdfdb9ec9b3b0fb08c15cbf9d2e282201ff33
