vhost-user-blk: fix blkcfg->num_queues endianness
Treat the num_queues field as virtio-endian. On big-endian hosts the vhost-user-blk num_queues field was in the wrong endianness. Move the blkcfg.num_queues store operation from realize to vhost_user_blk_update_config() so feature negotiation has finished and we know the endianness of the device. VIRTIO 1.0 devices are little-endian, but in case someone wants to use legacy VIRTIO we support all endianness cases.
