[SOCK]: Enumerate struct proto-s to facilitate percpu inuse accounting (v2).
The inuse counters are going to become a per-cpu array. Introduce an
index for this array on the struct proto.
To handle the case of proto register-unregister-register loop the
bitmap is used. All its bits manipulations are protected with
proto_list_lock and a sanity check for the bitmap being exhausted is
also added.
