nb_rxd and nb_txd are used in polling mode and event mode of
operation. nb_rxd and nb_txd are already global. Make them
visible to all parts of the application.

DTS test cases require changing the RX and TX queue depths.
Currently, this is achieved by patching the DPDK code. This patch set
provides a mechanism to configure the queue depths while launching
the application. With this change DTS test cases do not need
to modify the DPDK code.
