dev - Properly propogate wakeup events for ums

* The last commit had a minor problem.  It turns out that the
  selwakeup() code does not generate a kqueue event or wake it up
  if no select pid was set, and since select() now uses kqueue no
  select pid will ever be set.

* Calling KNOTE() directly solves the problem.
