drm/i915/gtt: Don't try to clear failed empty pd allocation
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) Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190719153322.10464-1-michal.wajdeczko@intel.com
