Hi All:

This series treis to do more hardening for virito.

patch 1 validates the num_queues for virio-blk device.
patch 2-4 validates max_nr_ports for virito-console device.
patch 5-7 harden virtio-pci interrupts to make sure no exepcted
interrupt handler is tiggered. If this makes sense we can do similar
things in other transport drivers.
patch 8-9 validate used ring length.

Smoking test on blk/net with packed=on/off and iommu_platform=on/off.

Please review.

Thanks
