[PATCH 2/2] examples/vm_power_manager: use safe version of list iterator

[Hamza Khan <hamza.khan@intel.com>]

Currently, when vm_power_manager exits, we are using a LIST_FOREACH
macro to iterate over VM info structures while freeing them. This
leads to use-after-free error. To address this, use the newly added
LIST_FOREACH_SAFE macro.
