[PATCH 6.1 280/609] drm/amdgpu/gfx11: replace BUG_ON() with WARN_ON()

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <[email protected]>

commit 0eebcab1ea2a77f086a04108f386f82ee3496022 upstream.

There's no need to crash the kernel for these cases.
