[dpdk-dev] [PATCH 1/4] examples/l3fwd-power: fix non Rx intr supported platform

This existing code cause the platform to start receiving packet
immediately irrespective of interrupts available or not.
If the platform does not support Rx interrupt, it shall not start
receiving packets immediately. It shall let the timer management work.
