It has been observed that for a specific network configuration, netifd
was not able to set the IPv6 to an interface during the reload
procedure. The only option, before this fix, is to use the restart
procedure which is not acceptible.
This fix disables configuring the IPv6 for a bridge member when it is
added to a bridge and enables IPv6 configuration when a member is
removed from a bridge.
