Hi:
This patch removes netlink_sock_nr which is only used by a printk
statement in af_netlink.c. Even that's only there if
NETLINK_REFCNT_DEBUG is defined.
If we were really looking for netlink refcnt bugs there are probably
better places to do that anyway.

Cheers,

Alternatively, how about enclosing them with NETLINK_REFCNT_DEBUG
for future reference?

Well if we really wanted to do refcnt debugging there then there are
much better ways to do it than this.
