virtio-ccw: support VIRTIO_QUEUE_MAX virtqueues
The maximal number of virtqueues per device can be limited on a per transport basis. For virtio-ccw this limit is defined by VIRTIO_CCW_QUEUE_MAX, however the limitation used to come form the number of adapter routes supported by flic (via notifiers). Recently the limitation of the flic was adjusted so that it can accommodate VIRTIO_QUEUE_MAX queues, and is in the meanwhile checked for separately too. Let us remove the transport specific limitation of virtio-ccw by dropping VIRTIO_CCW_QUEUE_MAX and using VIRTIO_QUEUE_MAX instead.
