radeonsi: apply the double EVENT_WRITE_EOP workaround to VI as well
Internal docs don't mention it, but they also don't mention that the bug has been fixed (like other CI bugs fixed in VI). Vulkan does this too. v2: also update r600_gfx_write_fence_dwords Cc: 13.0 <mesa-stable@lists.freedesktop.org> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> (v1)
