[PATCH v14 06/11] transport-mmio: Avoid referring to zero based index

[Parav Pandit <parav@nvidia.com>]

VQ range is already described in the first patch in basic virtqueue
section. Hence remove the duplicate reference to it.

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/163
Signed-off-by: Parav Pandit <parav@nvidia.com>

changelog:
v12->v13:
- corrected number to index
v11->v12:
- remove changes related to 'vq number'
v8->v9:
- added 'by' at two places
- replaced 'queue number' with 'vq number'

v6->v7:
- remove text around first vq as it is already covered in the basic
  virtqueues facility section
