Rob Bradford e8c72b1b01 virtio-devices: pci: Improve debugging for activation barriers 
On the CI we are seeing issues with the activation barriers not being released:

cloud-hypervisor: 12.452684596s: INFO:virtio-devices/src/transport/pci_device.rs:671 -- Waiting for barrier
cloud-hypervisor: 12.452708196s: INFO:virtio-devices/src/transport/pci_device.rs:673 -- Barrier released
cloud-hypervisor: 12.452717596s: INFO:vmm/src/vm.rs:415 -- Barrier released

Add some debugging to try and identify the vause of this issue.
