nir: fix assign_io_var_locations for vertex inputs
Also fixes fragment inputs using the wrong "base" value (which was working only because FRAG_RESULT_DATA0 is less than VARYING_SLOT_VAR0) Signed-off-by: Jonathan Marek <[email protected]> Reviewed-by: Eric Anholt <[email protected]> Tested-by: Marge Bot <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3108> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3108>
