anv: remove incorrect polygonMode=point early-out
This is incorrect, because polygonMode only applies if the final primitive type is a polygon; polygonMode doesn't apply to line-primitives as the comment suggests. The Vulkan 1.1 spec, section 26.11, "Polygons" defines that polygons are separate from points and line segments: " A polygon results from the decomposition of a triangle strip, triangle fan or a series of independent triangles. Like points and line segments, polygon rasterization is controlled by several variables in the VkPipelineRasterizationStateCreateInfo structure. " Further, section 26.11.2, "Polygon Mode", only define polygonMode to apply to polygons: " Possible values of the VkPipelineRasterizationStateCreateInfo::polygonMode property of the currently active pipeline, specifying the method of rasterization for polygons, are: " This seems to clearly define that polygonMode doesn't apply to points and lines, so let's make sure that we don't early out with the wrong value.
