net/enic: fix probe for secondary process

net/enic: fix probe for secondary process

Only the primary process initializes the adapter private data and
rte_eth_dev_data. For secondary processes, do not touch them.

Secondary processes need to select the right Tx and Rx handlers. Pick
the same handlers that the primary process uses.
