Currently, external memory API will silently succeed if the IOVA

Fix it so that if the IOVA addresses are provided, they are checked
to see if they fit into the DMA mask.

To avoid any misunderstandings, this is only for external memory - we
already do this for internal memory. See the original thread [1] for
context.
Also, needs Fixes: tag and a unit test, so will submit a v2 some time
this week.
