x86: cpumask: x86 mmio-mod.c use cpumask_var_t for downed_cpus
Impact: cleanup, reduce memory usage for CONFIG_CPUMASK_OFFSTACK=y
Part of the "getting rid of obsolete cpumask_t" patch:
1) Use cpumask_var_t: this is a pointer if CONFIG_CPUMASK_OFFSTACK=y
2) Call alloc_cpumask_var() on first entry into enter_uniprocessor()
3) Use modern cpumask_* functions.
