drm/i915: fix unused var
drivers/gpu/drm/i915/i915_dma.c: In function 'i915_driver_load':
drivers/gpu/drm/i915/i915_dma.c:1114: warning: 'll_base' may be used uninitialized in this function
Partly this is because gcc isn't smart enough. But `ll_base' does get used
uninitialised in the DRM_DEBUG() call.
