qemu: Add capability for vhost-user multiqueue
The support for this was added in QEMU with commit 830d70db692e374b55555f4407f96a1ceefdcc97. Unfortunately we have to do another ugly version-based capability check. The other option would be not to check for the capability at all and leave that to qemu as it's done with multiqueue tap devices. Signed-off-by: Martin Kletzander <mkletzan@redhat.com>
