freedreno: Assert that we don't exceed constlen.
We actually could go up to vs->constlen in the binning shader on a6xx,
but for sanity let's make sure that we're always under constlen. This
would have caught the bug fixed in 572c76fd8826 ("freedreno: Clamp UBO
uploads to the constlen decided by the shader.")
