CSIT-1325 - FIX: AVF tests failing on unbind
Currently there is and issue when consecutive AVF suites are
trying to initialize AVF and bind VF to vfio-pci driver, there
seems to be race condition if VPP has already VFs allocated.
This patch should introduce safer contstrain to disable VPP prior
AVF init.
