[Crash-utility] [PATCH 2/3] 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 to find 
another way to get online-CPUs number for crash utility.

This patch uses cpu_active_mask to get that value.
