drm/i915/gtt: Don't try to clear failed empty pd allocation

Browse source

When __gen8_ppgtt_alloc fails without allocating anything
we should not try to call __gen8_ppgtt_clear as there is
nothing to clear and underlying code will complain with:

[  157.861645] gen8_pd_range:881 GEM_BUG_ON(start >= end)
