net: Don't register pernet_operations if only one of id or size is specified.
We can allocate per-netns memory for struct pernet_operations by specifying
id and size.
register_pernet_operations() assigns an id to pernet_operations and later
ops_init() allocates the specified size of memory as net->gen->ptr[id].
If id is missing, no memory is allocated. If size is not specified,
pernet_operations just wastes an entry of net->gen->ptr[] for every netns.
net_generic is available only when both id and size are specified, so let's
ensure that.
While we are at it, we add const to both fields.
