i965: Fix instanced geometry shaders on Gen8+.
Jordan added this in commit 741782b5948bb3d01d699f062a37513c2e73b076 for Gen7 platforms. I missed this when adding the Broadwell code. Fixes Piglit's spec/arb_gpu_shader5/invocation-id-{basic,in-separate-gs} with MESA_EXTENSION_OVERRIDE=GL_ARB_gpu_shader5 set.
