[SOCK][NETNS]: Add the percpu prot_inuse counter in the struct net.
Such an accounting would cost us two more dereferences to get the percpu variable from the struct net, so I make sock_prot_inuse_get and _add calls work differently depending on CONFIG_NET_NS - without it old optimized routines are used. The per-cpu counter for init_net is prepared in core_initcall, so that even af_inet, that starts as fs_initcall, will already have the init_net prepared.
