Ensure that we make a netns for CNI non-default nets
We accidentally patched this out trying to enable ns:/path/to/ns This should restore the ability to configure nondefault CNI networks with Podman, by ensuring that they request creation of a network namespace. Completely remove the WithNetNS() call when we do use an explicit namespace from a path. We use that call to indicate that a netns is going to be created - there should not be any question about whether it actually does. Fixes #2795 Signed-off-by: Matthew Heon <mheon@redhat.com>
