vulkan: skip all-negative-inf blocks in FA

[jeffbolznv]

Fixes #17033. See #17033 (comment).

Overhead for this check generally seems low enough. Perf for just one parallel prompt in llama-batched-bench is a little lower for coopmat2 mode, but I think it's OK. The scalar path is slower due to increased register usage decreasing occupancy. I've filed an internal bug about that, but I'm not too worried about it since I think it only affects Blackwell and the scalar path isn't used for prompt processing on NVIDIA. Would be good to spot check perf on other HW.
