Currently the IP address event handlers bail out when the event is related
to a netdevice that is a bridge port or a member of a LAG. In order to
create a RIF when a bridged or LAG'd port is unenslaved, these event
handlers will be replayed. However, at the point in time when the
NETDEV_CHANGEUPPER event is delivered, informing of the loss of
enslavement, the port is still formally enslaved.

In order for the operation to have any effect, these handlers need an extra
parameter to indicate that the check for bridge or LAG membership should
not be done. In this patch, add an argument "nomaster" to several event
handlers.
