In a multi-site synchronization environment, the bucket full sync process will send a bucket list request to the remote, but the remote execution of the bucket list operation is likely to delete the object key.
for example:
t1 object upload-start [rgw_bucket_dir_entry.exists =false] （put obj）
t2 list bucket opreate start find 'rgw_bucket_dir_entry.exists=false'，and get_obj_state() return noevent. (list bucket)
t3 object upload-end ，[rgw_bucket_dir_entry.exists =true],(put obj)
t4 list bucket remove object key because t2.(list bucket)
You can add code like diff.txt to reproduce it.
