sched: convert struct cpupri_vec cpumask_var_t.
Impact: stack usage reduction, (future) size reduction for large NR_CPUS.
Dynamically allocating cpumasks (when CONFIG_CPUMASK_OFFSTACK) saves
space for small nr_cpu_ids but big CONFIG_NR_CPUS.
The fact cpupro_init is called both before and after the slab is
available makes for an ugly parameter unfortunately.
We also use cpumask_any_and to get rid of a temporary in cpupri_find.
