cpumask: convert node_to_cpumask_map[] to cpumask_var_t
Impact: reduce kernel memory usage when CONFIG_CPUMASK_OFFSTACK=y Straightforward conversion: done for 32 and 64 bit kernels. node_to_cpumask_map is now a cpumask_var_t array. 64-bit used to be a dynamic cpumask_t array, and 32-bit used to be a static cpumask_t array.
