From: Nicolai Hähnle <nicolai.haeh...@amd.com>
That format has first_non_void < 0. This fixes a regression in piglit
arb_shader_image_load_store-semantics that was introduced by commit 76b8c5cc602,
while hopefully still shutting Coverity up (and failing in a more obvious way
if a similar error should re-appear).
