Fade data buffers not provided when they are expected by the shader

[ksuprynowicz]

Fade on gpu::Batch::COMMAND_drawIndexed call provides only GPU_ATTR_FADEDATA1 instead of GPU_ATTR_FADEDATA1...7.

ERROR: [-862178626][VUID-VkGraphicsPipelineCreateInfo-Input-07904] : vkCreateGraphicsPipelines(): pCreateInfos[0].pVertexInputState->pVertexAttributeDescriptions does not have a Location 9 but vertex shader has an input variable at that Location. (This can be valid if either the vertexAttributeRobustness or maintenance9 feature is enabled).
The Vulkan spec states: If the vertexAttributeRobustness feature is not enabled, and the maintenance9 feature is not enabled, and the pipeline is being created with vertex input state and pVertexInputState is not dynamic, then all variables with the Input storage class decorated with Location in the Vertex Execution Model OpEntryPoint must contain a location in VkVertexInputAttributeDescription::location (https://docs.vulkan.org/spec/latest/chapters/pipelines.html#VUID-VkGraphicsPipelineCreateInfo-Input-07904)

Shader is simple_fade.vert and fimple_fade.vert.
