When a bridge binding flag is changed for a vlan interface, the
vlan_dev_change_flags function in the 8021q module is called. Currently, this
function only sets the flag for the vlan interface and returns, which results in
a buggy behavior; it also needs to let the bridge module module know that upper
device for the bridge has changed by propagating NETDEV_CHANGEUPPER event. This
event can be triggered using call_netdevice_notifiers_info function, so export
this function.
