[UNIKRAFT PATCH RFCv4 30/35] plat/virtio_9p: Remove excessive check for max virtqueue size

[Jia He <justin.he@xxxxxxx>]

For qemu virtio mmio read with VIRTIO_MMIO_QUEUE_NUM_MAX, it will
unconditionally return VIRTQUEUE_MAX_SIZE(1024) unlike virtio pci.
But it can set the number of queue size when seting up the virtqueue.
See vm_setup_vq which will be fixed in coming patch.

So the excessive check in virtio 9p is not necessary.
