ir3/spill: Mark root as non-spillable after inserting

We have to mark the root as non-spillable in case the interval is the
child of some other interval, but we can't know whether it's the child
of some other interval until it's been inserted. Move the setting of
cant_spill below the insertion. This prevents us from using a bogus
parent value.
