Is nt defined instead of !defined?

Use bracket around RTE_GRAPH_MODEL_SELECT == RTE_GRAPH_MODEL_RTC.

Use bracket around RTE_GRAPH_MODEL_SELECT ==

Introduce rte_graph_worker_model_no_check_get() as commented earlier.

I think, switch case better to support new model in future. Please
check the performance before changing.

i.e

switch ( rte_graph_worker_model_no_check_get())
{
case RTE_GRAPH_MODEL_MCORE_DISPATCH:
        rte_graph_walk_mcore_dispatch(graph)
        break;
default:
       rte_graph_walk_rtc(graph);
}
