check  cores is necessary before using these cores.
dpdk commit b49c677 said  " 
    When vm_power_manager is started, it takes over power management on
    all cores. This should be limited to cores defined in the core mask.

    When initialising, if a core is not on the coremask, skip it.
    Applies to both initialisation and exit."
So, please go through script, don't missing any other places. The cores that not on core mask will be not taken over by app.
