cls/user: cls_user_set_buckets_info overwrites creation_time

metadata sync of a new bucket entrypoint may call rgw_link_bucket()
(which in turn calls into cls user) without deleting/unlinking the
previous bucket entrypoint. this prevented the new bucket entrypoint
from overwriting the creation_time of the old one
