examples/power: fix core id with JSON commands

Browse Source 
This patch fixes a bug introduced in the 64-core limitation
enhancement where the core_id is inadvertently converted from
virtual to physical even though it may already be a physical
core_id.

We should be using the core_type field, and only converting via
hypervisor when core_type is set to CORE_TYPE_VIRTUAL

Fixes: 5776b7a371 ("examples/power: allow VM to use lcores over 63")
