vlib: fixed the issue of vpp crash caused by interface up/down
When the interface status changes, the api of vnet_hw_interface_set_flags_helper calls the event processing function (vlib_process_signal_event_helper) for event processing. When the opinter data_vec is NULL, the _ven_len operation of an illegal address will cause vpp crash.
Type:fix
