net/null: fix multi-process Rx and Tx

Browse Source 
Packet processing in secondary process cannot work because rx_pkt_burst
and tx_pkt_burst in eth_dev are not initialized while probing device.
This patch is to the initialization.

Fixes: ee27edbe0c ("drivers/net: share vdev data to secondary process")
