Public bug reported:

Using the ml2 neutron plugin, if a port binding fails, the port
attribute vif_type is set to portbindings.VIF_TYPE_BINDING_FAILED.

After this happens, nova fails to unplug that port during cleanup,
raising a new exception in
nova.virt.libvirt.vif.LibvirtGenericVIFDriver.unplug. This exception
then hides the original failure.

A solution should be just defining a no-op unplug_binding_failed method
in that class, as nothing is to be done in that case anyway.
