netlink_proto_init and sock_init

[Octavian Purdila <tavi@cs.pub.ro>]

Hi,

I've noticed that with some exotic build setups (e.g. mingw) 
netlink_proto_init is called before sock_init and subsequently sock_alloc 
runs into a NULL sock_mnt. The following patch seems to fix the problem, but 
I'm not sure if this is the right thing to do, as there are no _initcall_sync 
calls in the kernel yet. 

Thanks,
tavi

    sock_init needs to be called before netlink_proto_init, but both
    sock_init and netlink_proto_init share the same init level
    (core). Move netlink_proto_init to sync core level.
