radosgw record wrong data logs when create and delete bucket in seconds repeatedly
first, enable data log and meta log for multisite.
second, create a bucket and an object, then delete the object and the bucket.repeat this process for a few times.
third, get the data log from rgw. the data log maybe contains the first created bucket's id, but no the last created bucket id.
when multisite is configured, the synchronization will be wrong between zones. radosgw zone rely on the correct data log.
