When PF event VIRTCHNL_EVENT_LINK_CHANGE received, i40evf need update
the link status and issue RTE_ETH_EVENT_INTR_LSC via
_rte_eth_dev_callback_process().

The implementation is incomplete, 

To support LSC in i40evf, please
1. add RTE_PCI_DRV_INTR_LSC in drv_flags
2. make sure dev_conf.intr_conf.lsc can be configure with 1
3.update i40e_vf.ini.
