sched: convert struct root_domain to cpumask_var_t.
Impact: (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. cpumask_var_t
is just a struct cpumask for !CONFIG_CPUMASK_OFFSTACK.
def_root_domain is static, and so its masks are initialized with
alloc_bootmem_cpumask_var. After that, alloc_cpumask_var is used.
