virtio: Revert "virtio: find_vqs() add arg sizes"
This reverts commit a10fba0377145fccefea4dc4dd5915b7ed87e546: the proposed API isn't supported on all transports but no effort was made to address this. It might not be hard to fix if we want to: maybe just rename size to size_hint and make sure legacy transports ignore the hint. But it's not sure what the benefit is in any case, so let's drop it. Fixes: a10fba037714 ("virtio: find_vqs() add arg sizes") Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Message-Id: <20220816053602.173815-8-mst@redhat.com>
