The enic DMAs link status information to the host and this requires a
little setup. This setup was being done as a result of calling
rte_eth_dev_start(). But applications expect to be able to check link
status before calling rte_eth_dev_start().
This patch moves he link status setup to enic_init() which is called
at device probe time so that link status can be checked anytime.
