Subject: sched: convert check_preempt_equal_prio to cpumask_var_t.

sched: convert check_preempt_equal_prio to cpumask_var_t.

Impact: stack reduction for large NR_CPUS

Dynamically allocating cpumasks (when CONFIG_CPUMASK_OFFSTACK) saves
stack space.

We simply return if the allocation fails: since we don't use it we
could just pass NULL to cpupri_find and have it handle that.
