Description of problem:
When live migrating a VM with several SR-IOV network interfaces, some of the NICs fail to be attached in the target host with this error:

Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainMigratePrepare3Params)

It looks like virt-launcher tries to hot-plug the host-devices in a stage too early, when the lock is held by remoteDispatchDomainMigratePrepare3Params where domain modification is not allowed.

Version-Release number of selected component (if applicable):
OpenShift 4.10.23
kubevirt-hyperconverged-operator.v4.10.3
sriov-network-operator.4.10.0-202207192148

How reproducible:
Always in customer environment.

Steps to Reproduce:
1. Have a VMI with several SR-IOV NICs:

~~~
interfaces:

• bridge: {}
  macAddress: aa:bb:cc:dd:ee:00
  model: virtio
  name: nic-1
• macAddress: aa:bb:cc:dd:ee:01
  model: virtio
  name: nic-2
  pciAddress: "0000:20:00.0"
  sriov: {}
• macAddress: aa:bb:cc:dd:ee:02
  model: virtio
  name: nic-3
  pciAddress: "0000:21:00.0"
  sriov: {}
• macAddress: aa:bb:cc:dd:ee:03
  model: virtio
  name: nic-4
  pciAddress: "0000:22:00.0"
  sriov: {}
• macAddress: aa:bb:cc:dd:ee:04
  model: virtio
  name: nic-5
  pciAddress: "0000:23:00.0"
  sriov: {}
• macAddress: aa:bb:cc:dd:ee:05
  model: virtio
  name: nic-6
  pciAddress: "0000:24:00.0"
  sriov: {}
• macAddress: aa:bb:cc:dd:ee:06
  model: virtio
  name: nic-7
  pciAddress: "0000:25:00.0"
  sriov: {}
  ~~~

2. Live migrate the VM
3. After the migration, verify if the VM has all the NICs connected and check the virt-launcher pod log

Actual results:
Some hot-plug operations fail:

Expected results:
NICs attached successfully

Additional info:
There are some recent changes in how the SR-IOV devices are attached:

https://github.com/kubevirt/kubevirt/pull/6581

Can they be backported to 4.10?
