Fuel-QA: OSTF test fails if DPDK for bond with private network is enabled on all computes

[Tatyana Kuterina]

Detailed bug description:
Found on CI:
https://product-ci.infra.mirantis.net/job/9.0.system_test.ubuntu.support_dpdk_bond/65/console

Test: Deploy cluster with DPDK, active-backup bonding and Neutron VLAN
Test Group: deploy_cluster_with_dpdk_bond

Steps to reproduce:
        1. Create cluster with VLAN for Neutron and KVM
        2. Add 1 node with controller role
        3. Add 2 nodes with compute and cinder roles
        4. Setup bonding for all interfaces: 1 for admin, 1 for private
           and 1 for public/storage/management networks
        5. Configure HugePages for compute nodes
        6. Enable DPDK for bond with private network on all computes
        7. Run network verification
        8. Deploy the cluster
        9. Run network verification
        10. Run OSTF
Expected results:
   All OSTF tests are finished without errors
Actual result:
   1 OSTF test: Launch instance, create snapshot, launch instance from snapshot is finished with errors

Description of the environment:
9.0 GA + snapshot #25

I think we can consider this issue as Invalid for now, because three runs were successful:
