cpumask: Use nr_cpu_ids in seq_cpumask
Impact: cleanup, futureproof
nr_cpu_ids is the (badly named) runtime limit on possible CPU numbers;
ie. the variable version of NR_CPUS.
With the new cpumask operators, only bits less than this are defined.
So we should use it everywhere, rather than NR_CPUS. Eventually this
will make it possible to allocate cpumasks of the minimal length at runtime.
