pull or pod create: Error creating cache file for layer "x": locating layer with ID "x": layer not known

[edsantiago]

Yet another "layer not known" flake seen in parallel CI testing:

# podman --noout pod create --name p-t181-wdhsgkec --infra-name infra_container_t181-wdhsgkec --infra-image quay.io/libpod/k8s-pause:3.5

or on pull:

# podman pull quay.io/libpod/alpine:latest

Both are warnings, not errors. The command succeeds, but test fails because of undesired warnings.
