Subject: [PATCH] nak: sm50: fix ineg legalization

There is nothing to be done, as we lower this op unconditionally.

We need to add an arm in the match to not panic, though.

Fixes a panic in
dEQP-VK.binding_model.shader_access.primary_cmd_buf.sampler_immutable.vertex_fragment.multiple_contiguous_descriptors.2d
