John Baldwin 9fc9d84b9b - Use callout_init_mtx() to initialize toffhandle callout using the fdc's ...

mutex.
- Don't use callout_drain() to stop the toffhandle callout while holding the
  fdc mutex (this could deadlock) in functions called from softclock
  (callouts aren't allowed to do voluntary sleeps).  Instead, use
  callout_stop().  Note that since we hold the associated mutex and are now
  using callout_init_mtx(), callout_stop() is just as effective as
  callout_drain().  (Though callout_drain() is still needed in detach to
  make sure softclock isn't contesting on our mutex before we destroy the
  mutex.)
- Remove unused callout 'tohandle' from softc.
