    Revert "intel/nir: Call nir_lower_io_to_scalar_early"

    Commit 4434591bf56a6b0 caused substantially more URB messages in
    geometry and tessellation shaders.  Before we can really enable this
    sort of optimization,  We either need some way of combining them back
    together into vectors or we need to do cross-stage vector element
    elimination without splitting everything into scalars.
