Since LSR interrupt is disabled by pmd drivers, link status in rte_eth_device is always down. Bond slave_configure() enables LSR interrupt on devices to get notification if link status changes. However, the LSC interrupt at device start time is still lost.
In this fix, call link_update to read link status from hardware register at device start time.
