IRQ_MOVE_CLEANUP_VECTOR is the only one of the system IRQ vectors that

This is a complete NOOP on not FRED enabled systems as the IDT entry is
still separate. So this change makes no sense outside of the FRED
universe. Can we pretty please make this consistent?
The right thing to make this consistent is to get rid of this vector
completely.
There is zero reason for this to be an IPI. This can be delegated to a
worker or whatever delayed mechanism.
As we discussed offline, I agree that this is a better solution (and
should be a separate changeset before the FRED one.)
