nir/scheduler: Handle nir_intrinsic_load_per_vertex_input

load_per_vertex_input should probably be handled in the same way as a
regular load_input. I think the nir_schedule pass was written before V3D
had geometry shader support, so that is probably why it hasn’t taken
this into account until now.
