bonding: remove rtmsg_ifinfo called in bond_master_upper_dev_link
Since commit 42e52bf9 ("net: add netnotifier event for upper device change"), netdev_master_upper_dev_link has generated NETDEV_CHANGEUPPER event which would send a notification to userspace in rtnetlink_event. There's no need to call rtmsg_ifinfo to send the notification any more. So this patch is to remove it from bond_master_upper_dev_link as well as bond_upper_dev_unlink to avoid the redundant notifications.
