ospfd: ospfd crash while giving 'clear ip ospf neighbor'

Browse Source 
Description:
	Ospf process crashes upon giving 'clear ip ospf neighbor' with
        self routerId. It is asserting if it is a self neighbor in ospf
        neighbour kill event processing.
	Added a check to validate the provided router-id is self
        router-id.
