In nf_ct_l4proto_register_sysctl, if l4proto sysctl registration
fails, we have to make sure that we release the compat sysctl
table.

This can happen if TCP has been registered compat for IPv4, and
IPv6 compat registration fails.

Currently, nf_proto_net's l4proto->users meaning is quite confusing
since it depends on the compilation tweaks.

To resolve this, we cleanup this code to regard it as the refcount
for l4proto's per-net data, since there may be two l4protos use the
same per-net data.

Thus, we increment pn->users when nf_conntrack_l4proto_register
successfully, and decrement it for nf_conntrack_l4_unregister case.

The users refcnt is not required form layer 3 protocol trackers.

This patch is a cleanup.

Before commit 2c352f44
(netfilter: nf_conntrack: prepare namespace support for
l4 protocol trackers), we register sysctl before register
protocol tracker. Thus, if sysctl is registration fails,
the protocol tracker will not be registered.

After that commit, if sysctl registration fails, protocol
registration still remains, so we leave things in intermediate
state.

To fix this, this patch registers sysctl before protocols.
And if protocol registration fail, sysctl is unregistered.
