Starting with v2.0, <DATAROOT>/<ADDRHASH>/names/<NAMESPACE> is accidentally created as <DATAROOT>/<ADDRHASH>/<NAMESPACE>.

e.g.,

/var/lib/nerdctl/1935db59/default/foo

Caused by bf89c08#diff-7e8241ea95018a415ccbb4d0697f2842179f62d2a4b968671d4ebdb962f2e11aL32

Fixing this regression can be also a breaking change for existing containers, so this regression should not be fixed in a patch release?
