Zhenghua Zhou 653c6ed4a1 app/testpmd: do not allow dynamic change of core number
When the number of forwarding cores changed in runtime, the issue may
be encountered:
If the nbcore set little than current nbcore, the forwarding thread
will still running on the extra cores. Therefore, trying to stop
forwarding will hang testpmd, since it will wait for the extra cores to
stop.

So do not allow to change nbcore number when forwarding is running.
