Description

podman pod create --uts doesn't work on remote environment.
.InfraConfig.uts_ns field sets private even if --uts ns:<ns path>.

Steps to reproduce the issue:

1. Create the new pod with --uts ns:<ns path>

# podman-remote pod create --uts ns:/proc/self/ns/ --name utsPod --share uts
30254e9b42870e7f010132006927ccc23aebe5ec93d4871716d67d83394d1e0f

2. Inspect the created pod

# podman-remote pod inspect utsPod
