When instantiating an instance based on an image with the metadata
hw_vif_multiqueue_enabled=true, if flavor.vcpus is less than the limit
of the number of queues on a tap interface in the kernel, nova uses
flavor.vcpus as the number of queues. if not, nova uses the limit.
The limits are as follows:
* kernels prior to 3.0: 1
* kernels 3.x: 8
* kernels 4.x: 256
