net/i40e: fix VF link status update

VF link status rely on PF's notification, so when PF link status
be updated, it should notify VF to update link status also.
Current implementation only cover part of the situation when PF's link
status is updated, call i40e_notify_all_vfs_link_status in
i4e_dev_link_update will cover all situationa.
