Matthew Auld 31444afb46 drm/i915: s/for_each_sgt_dma/for_each_sgt_daddr/ 
The sg_table for our backing store might contain addresses from
stolen-memory or in the future local-memory, at which point this is no
longer a dma-iterator. As a consequence we should now break on NULL
iter.sgp, instead of dmap == 0 which is considered an invalid dma
address.

As a bonus, gcc much prefers this construct,

  Function                                     old     new   delta
