[Rebalance][Windows] : Delta Recovery rebalance fails with Rebalance exited with reason {{badmatch, {error,marking_as_warmed_failed, ['ns_1@172.23.136.134']}}, [{ns_rebalancer, '-apply_delta_recovery_buckets/3-fun-0-',2, [{file,"src/ns_rebalancer.erl"},

Steps to repro

1. Created a 2 node cluster using Windows Server 2019 nodes on 7.2.0-5325
2. Loaded sample buckets and created a few buckets and loaded data
3. Upgraded the cluster to 7.2.3-6710 and continued data load during upgrade
4. Post upgrade performed a graceful failover of one of the nodes
5. Added it back with Delta recovery
6. Rebalance fails. A re-try of the rebalance succeeds
7. Failed the node over again and retried delta recovery, it succeeds

Tried to reproduce with the same cluster setup and the issue is not consistent ( as seen in the logs )
