For high throughput indexing, we version updates on the leader and
forward onto other replicas w/o strict serialization.
If on a leader, an add happened before a DBQ, then on a replica the
DBQ is serviced before the add, Solr detects this reordering and fixes
it.
It's not an error or an indication that anything is wrong (hence the
INFO level log message).
