drm/i915: less magic for stolen preallocated objects w/o gtt offset
A magic -1 is a obscure, especially since it's actually passed as an
unsigned, so depends upon the magic sign extension rules in C. This has
been added in

drm/i915: allow stolen, pre-allocated objects to avoid GTT allocation v2
Use a proper #define instead. Spotted while reviewing Ben's
drm_mm_create_block changes.
v2: Cast the constant to u32 since otherwise we again have a type
mismatch. Suggested by Chris Wilson.
