examples/vm_power: fix physical core mask

Host cpu mapping structure can only support 64 cpus. When run vm_power sample
on platform with more than 64 cpus, will generate improper physical core mask.
After limited supported host cpus to 64 will fix this issue.

Fixes: e9f64db94637 ("examples/vm_power: show warning when more than 64 cores")
