Jerin Jacob cb327a7802 mbuf: reduce pktmbuf init cycles 
There is no need for initializing the complete
packet buffer with zero as the packet data area will be
overwritten by the NIC Rx HW anyway.

The testpmd configures the packet mempool
with around 180k buffers with
2176B size. In existing scheme, the init routine
needs to memset around ~370MB vs the proposed scheme
requires only around ~22MB on 128B cache aligned system.

Useful in running DPDK in HW simulators/emulators,
where millions of cycles have an impact on boot time.
