cluster/tier: Create linkfiles to hardlinks correctly

There is a bug in the way hardlinks are handled in tiered volumes.
Ideally, the tier linkto files on the cold tier to files that are
hardlinks to each other on the hot tier, should themselves be
hardlinks of each other. As they are not, they end up being files
with the same gfid but different names for the cold tier dht,
and end up overwriting the cached-subvol information stored in the dht inode-ctx.
