When reading the mount path here it can be missing and thus fail with
ENOENT when the voluem is removed in parallel. Because we do not want to
block for a full directory walk of course with the volume lock the only
choice is to ignore the error.
I have seen this error many times in CI in the past weeks:
FAIL: podman system df --format '{{"\n"}}'
expected: = ''
actual: Error: lstat /home/ubuntu.guest/.local/share/containers/storage/volumes/v-t450-1djh1zmh/_data: no such file or directory
