kernel - Fix callout structural corruption bug

* _callout_cancel_quick() was not properly testing whether
  the callout being canceled matched sc->next, resulting
  it occassional kernel panics under certain circumstances.

* Could be triggered during dsynth runs.

* Fixed by adding the proper test.
