credit2: Add context_saved scheduler callback
Because credit2 shares a runqueue between several cpus, it needs
to know when a scheduled-out process has finally been context-switched
away so that it can be added to the runqueue again. (Otherwise it may
be grabbed by another processor before the context has been properly
saved.)
