Handle creation of Port_Binding with chassis set

When there is a backlog of notifications to be sent, it is possible
that ovsdb-server will merge insert and update notifications. Due
to this, we need to handle the situation where we see a Port_Binding
created with the chassis set.

Closes-Bug: #2017748
