Of the 3 virtqueues, seabios only sets cmd, leaving ctrl
and event without a physical address. This can cause
vhost_verify_ring_part_mapping to return ENOMEM, causing
the following logs:
qemu-system-x86_64: Unable to map available ring for ring 0
qemu-system-x86_64: Verify ring failure on region 0
This has already been fixed for vhost scsi devices and was
recently vhost-user scsi devices. This commit fixes it for
vhost-user-blk devices.
