Upon updating a container, if its network namespace has been
removed, we attempt to clean up the network namespace locally,
to ensure we don't leave hanging file descriptors. This triggers
cleanup code which assumes the network namespace still exists,
but it almost certainly was removed by whoever removed it from
the database. As such, we end up with unavoidable errors if we
don't want to leak FDs. Make these errors nonfatal and log them
because of this.
