Remove assert on duplicate GPU Address ranges

* It's valid to have overlapping buffers on a heap, which could end up with
  overlapping ranges.
* It's impossible from the API to tell which buffer an address came from if
  there are multiple possibilities, but any of them will be technically correct,
  we just might display a different buffer than the user expected.
