Bug Description

When VM create failed (such as "_create_domain" execute failed), do not unplug-ports. This bug hit all release/branch.

When create the VM, It will update network-info at the process "update_instance_cache_with_nw_info".
But It only update the data in Data-base. the InstanceInfoCache of the local variable(instance) do not be updated.

If the VM is created failed at process "libvirt.driver._create_domain".
when shutdown the instance,it can not get the correct network information
So can not unplug-vif correctlly, there are some information is left

So when shutdown the instance, get to the wrong network information
