Summary: In CompactionManifestWriteRetryableError in error_handler_fs_test, the manifest write of flush should pass with no fs error. After flush, fs is set to error status and the manifest write of compaction should fail due to the IO Error. Currently, the manifest write of flush is not synced with the compaction in order, which might cause manifest write fails, which will cause test failure. Fixed by adding the LoadDependency of sync-point after flush and before compaction. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6637 Test Plan: pass error_hanlder_fs_tes.
