Shard split doesn't work when shard has NRT and pull replica and prs is enable on collection

To reproduce shard shard split scenario

1. create a collection with PRS enable
2. create shard with NRT and pull replica
3. execute a shard split cmd
4. result: subshard will not become active

Problem: We observed that prs state of replica is updated by data node. But overseer node doesn't listen/read that updated prs state of replica. because of that subshard remains inactive after shard split.
