anv/pipeline: Don't look at blend state unless we have an attachment
Without this, we may end up dereferencing blend before we check for
binding->index != UINT32_MAX. However, Vulkan allows the blend state to
be NULL so long as you don't have any color attachments. This fixes a
segfault when running The Talos Principal.
