Subject: [PATCH 210/212] cluster/ec: send list-node-uuids request to all
 subvolumes

The xattr trusted.glusterfs.list-node-uuids was only sent to a single
subvolume. This was returning null uuids from the other subvolumes as
if they were down.

This fix forces that xattr to be requested from all subvolumes.
