Commit Message

[FIXED] Concurrent map iter/write for WQ stream unique consumer partition (#7708)

There's a `fatal error: concurrent map iteration and map write` when
ranging over the `mset.consumers` in `mset.partitionUnique`.

The stream lock must be held when calling `mset.partitionUnique`. The
consumer read lock must also be held when reading and iterating over
`o.subjf`.

Resolves https://github.com/nats-io/nats-server/issues/7707
