qed: Multiple qzone queues for VFs
This adds the infrastructure for supporting VFs that want to open
multiple transmission queues on the same queue-zone.
At this point, there are no VFs that actually request this functionality,
but later patches would remedy that.
a. VF and PF would communicate the capability during ACQUIRE;
Legacy VFs would continue on behaving as they do today
b. PF would communicate number of supported CIDs to the VF
and would enforce said limitation
c. Whenever VF passes a request for a given queue configuration
it would also pass an associated index within said queue-zone
