[Mesa-dev] [PATCH 3/4] radv: do not update the number of viewports in vkCmdSetViewport()

[Samuel Pitoiset]

The Vulkan spec (1.0.61) says:

   "The number of viewports used by a pipeline is still specified
   by the viewportCount member of VkPipelineViewportStateCreateInfo."

So, the number of viewports is defined at pipeline creation
time and shouldn't be updated when they are set dynamically.
