igt/gem_streaming_writes: Bind into the GTT early
If we are using a streaming GGTT write into the source, we need to trigger an early fault in order to obtain a mappable offset. This is required when later we start reserving execbuf object top-down to try and avoid mappable space! Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
