Yi Wu 83b991922e Fix EncryptedEnv assert (#5735)
Summary:
Fixes https://github.com/facebook/rocksdb/issues/5734. By reading the code the assert don't quite make sense to me, since `dataSize` and `fileOffset` has no correlation. But my knowledge about `EncryptedEnv` is very limited.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/5735

Test Plan:
run `ENCRYPTED_ENV=1 ./db_encryption_test`
