VRF: Fix issues with reconfiguration

Browse Source 
Protocols receive if_notify() announcements that are filtered according
to their VRF setting, but during reconfiguration, they access iface_list
directly and forgot to check VRF setting here, which leads to all
interfaces be addedd.

Fix this issue for Babel, OSPF, RAdv and RIP protocols.

Thanks to Marcel Menzel for the bugreport.
