[Qemu-trivial] [PATCH Trivial] hw/intc/arm_gic: Use pre-defined macro for cpu_num in code

[Wei Huang <wei@redhat.com>]

Given that there is a macro, NUM_CPU(s), defined for CPU number in
arm_gic.c, it is better to use it instead of using s->num_cpu in
this file. Code is more consistent after this change.
