with [:cpuspec] struct/union/* will display per-cpu structure/union of the
specified cpus. This patch will hide data of offline cpus.
The original output is like below:
<cut>
crash> call_function_data 15080:a
[0]: ffff88003fc15080
struct call_function_data {
csd = 0x177e8,
...
cpumask = 0xffff88003daf4000,
cpumask_ipi = 0xffff88003daf4400
}
[2]: ffff88003fd15080
struct call_function_data {
csd = 0x18248,
cpumask = 0xffff88003daf4800,
cpumask_ipi = 0xffff88003daf4c00
}
[3]: ffff88003fd95080
...
<cut>
With data of offline cpu(cpu #2) hiden, the output is like below:
<cut>
crash> call_function_data 15080:a
[0]: ffff88003fc15080
struct call_function_data {
csd = 0x177e8,

}
