[PATCH] drm/i915: Update gen8_ppgtt_info to keep working in full ppgtt

[Michel Thierry <michel.thierry@intel.com>]

The driver will no longer initialize the aliasing ppgtt if we have
full ppgtt enabled.

gen8_ppgtt_info uses the aliasing ppgtt or the ppgtt from the
default context. This patch makes it clear.
