Fix reporting of EC shard sizes from nodes to masters. (#7835)

SeaweedFS tracks EC shard sizes on topology data stuctures, but this information is never
relayed to master servers :( The end result is that commands reporting disk usage, such
as `volume.list` and `cluster.status`, yield incorrect figures when EC shards are present.

As an example for a simple 5-node test cluster, before...

```
