Make sure to always explicitly set namespace for all kernel bound network operations irrespective of whether the operation is performed in init namespace or a user defined namespace. This already happens for user defined netns. But doesn't happen for initial netns that libnetwork runs in. Signed-off-by: Jana Radhakrishnan <mrjana@docker.com>
