Bug 7055: Interface removals donot keep Op DS and Cfg DS consistent.

Southbound driven interface removals (if northbound
port-delete gets delayed), fail to keep the
operational and config DS in sync.

This fix makes sure the missing operTxn submission
happens and it happens before the config DS submission.
