iris: Fix imageBuffer and PBO download.
Recently we added checks to try and deny multisampled shader images.
Unfortunately, this messed up imageBuffers, which have sample_count = 0,
which are also used in PBO download, causing us hit CPU map fallbacks.
Fixes: b15f5cfd20c iris: Do not advertise multisampled image load/store.
