[PATCH v2 1/2] drm/i915/gem: Return NULL instead of '0'

[Andi Shyti <andi.shyti@linux.intel.com>]

Commit 05da7d9f717b ("drm/i915/gem: Downgrade stolen lmem setup
warning") returns '0' from i915_gem_stolen_lmem_setup(), but it's
supposed to return a pointer to the intel_memory_region
structure.

Sparse complains with the following message:

>> drivers/gpu/drm/i915/gem/i915_gem_stolen.c:943:32: sparse: sparse:
   Using plain integer as NULL pointer

Return NULL.
