Subject: [PATCH 5.10 541/663] drm/i915/gt: Correct surface base address for renderclear

From: Chris Wilson <chris@...is-wilson.co.uk>

commit 81ce8f04aa96f7f6cae05770f68b5d15be91f5a2 upstream.

The surface_state_base is an offset into the batch, so we need to pass
the correct batch address for STATE_BASE_ADDRESS.
