[PATCH 5.11 644/775] drm/i915/gt: Correct surface base address for renderclear
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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.
