virtio-blk: should num_vqs be limited by num_possible_cpus()?
I observed that there is one msix vector for config and one shared vector
for all queues in below qemu cmdline, when the num-queues for virtio-blk
is more than the number of possible cpus:
qemu: "-smp 4" while "-device virtio-blk-pci,drive=drive-0,id=virtblk0,num-queues=6"
# cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3
