ModifiedNodeDoesNotExistException encountered while building Linkstate topology

Scenario is ODL has active connection with router and BGP-LS updates are received from router, from which the linkstate topology has been generated. Now due to issue in BUG-6577 if ODL encounters a NullPointerException, it starts reporting ModifiedNodeDoesNotExistException exceptions someafter. If size of linkstate topology is big as in real-life network, excessive number of ModifiedNodeDoesNotExistException messages are logged and data in linkstate topology is never fully recovered
