VM goes to error state when network is created with disable port security.

Steps to reproduce:

openstack network create network_1 --provider-network-type vxlan --disable-port-security

openstack subnet create --network network_1 --subnet-range 40.0.0.0/24 l2_subnet_1

openstack server create --image cirros --flavor m1.nano --nic net-id=network_1 MyFirstInstance_1 --security-group default (VM goes to error state)
