qede: Prevent VFs from using XDP
Current implementation of VFs is very tight in regard to queue
resources. VFs support for XDP would require quite a bit of additional
infrastructure in qede and qed [sharing of queue-zones between queues,
more VF cids, mapping of the doorbell bar, etc.].
For now, prevent XDP programs from being attached to VFs.
