cpumask: remove deprecated functions.
Using these functions with offstack cpus is unsafe. They use all NR_CPUS bits, unstead of nr_cpumask_bits. In particular, lustre (in staging) used cpus_ and that caused a bug. Reported-by: Oleg Drokin <green@linuxhacker.ru> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
