sk_protinfo, sk_slab, sk_zapped are going away when I finish my 
connection_sock-2.6 series.

sk_protinfo isn't needed if all proto families use the sk_alloc + kmalloc, i.e.
specifying the size of the proto specific socket (like tcp_sock) in
"zero_it"  and
passing NULL in the slab parameter, like I did with bluetooth today and will do
with the ham radio, the last ones using sk_protinfo.

sk_slab will be get from only in sk->sk_prot->slab.

sk_zapped was just a debugging member that got reused, and can be turned
into a SOCK_ZAPPED in sk_flags.
