Multicast unsubscribed after subscribing

This happens because route table subscribe walk is started without initializing
type of walk. In that case disassociate is issued resulting in unsubscription.
This issue will happen if this walk requests are processed after route
notification in controller. Notification would have done sub but walk will
unsub. If walk finishes before route notification then issue is not seen.
