vhost: fix range used in translate_desc()
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.
