chore(weed/topology): drop the unused DataNode volume id listing (#10618)

GetVolumeIds ranged over a slice and collected the loop indices, so it reported
0-99 rather than the node's volume ids. Nothing calls it: the disk-level
GetVolumeIds, which ranges over a map and is correct, is what ToDiskInfo and
ToMap use. Its private getVolumes helper went with it, having no other caller.
