test/dma: Add option to fail test if memory domains

Browse Source 
are not supported

That will be used to test memory domains with logical
volumes, we need to make sure that lvol correctly
reports memory domains. Also add a counter for the
number of translation_cb calls and verify that
it is not smaller than the total number of
completed IO requests
