[Crash-utility] [PATCH v2 3/4] crash: ARM: get online CPUs from cpu_active_mask

[Liu Hua]

For ARM32 platfrom, The system will "offline" all CPUs except the
crashing one, by clear the cpu_online_mask. So we need find another
way to get online-CPUs number for crash utility.

This patch uses MAX(get_cpus_active(),get_cpus_online()) to get that
value.
