[PATCH 09/10] drm/i915: Clear the pending_gpu_fenced_access flag at the start of execbuffer

Otherwise once we use the buffer with a BLT command on gen2/3, we will
always regard future command submissions as continuing the fenced
access. However, now that we flush/invalidate between every batch we can
drop this pessimism.
