vhost_iotlb_itree_first() requires `start` and `last` parameters
to search for a mapping that overlaps the range.
In translate_desc() we cyclically call vhost_iotlb_itree_first(),
incrementing `addr` by the amount already translated, so rightly
we move the `start` parameter passed to vhost_iotlb_itree_first(),
but we should hold the `last` parameter constant.
Let's fix it by saving the `last` parameter value before incrementing
`addr` in the loop.
