This prevents the modification of nf_conntrack_max in unprivileged network
namespaces. For unprivileged network namespaces, ip_conntrack_max is kept
as a readonly sysctl in order to minimize potential compatibility issues.

This patch should apply cleanly to the net tree.

For the record: This patch looks good to me, but this legacy
ip_conntrack sysctl code is now gone.

I don't know what is the procedure to get this to -stable branches now
that this cannot be pushed upstream.

In the commit message for the -stable submission simply say "Not
applicable" in the upstream commit reference.  Like:

	[ Upstream commit: Not applicable ]

or something like that.
