There is regression of hotplug removal of virtio-net-pci on q35
introduced long time ago in 3.0.0 with commit:
 48564041a73adbbff52834f9edbe3806fceefab7
 exec: reintroduce MemoryRegion caching

virtio-net does not destroy some of caching resources upon
hot unplug and on further hot plug the device with the same
name can not be added.
These 2 patches solve the problem.

Yuri Benditovich (2):
  virtio: reset region cache when on queue deletion
  virtio-net: delete also control queue when TX/RX deleted
