Bug Description

This is a bug in NEC Plugin.

While migrating vm, it's port information is deleted at the end of the migration sequence.
This makes a lack of port information and the port is never activated.
The problem is that quantum-server(nec-plugin) delete port information by receiving port_removed message from source host, even if the port still exists on destination host.

In vm migration sequence,
1. nova-compute creates a new port on destination host,
2. quantum-agent(nec) sends port_added message to qauntum-server(nec),
3. quantum-server(nec) updates port information,
4. (kvm migrates vm,)
5. nova-compute deletes old port on source host,
6. quantum-agent(nec) sends port_deleted message to qauntum-server(nec),
7. quantum-server(nec) deletes port information.

I can fix this bug in a small patch,
I hope that the bugfix will be backported into grizzly release.
