kernel - kqfilter - Fix edge-case lockup in kern_kevent()

* An edge case where the marker can wind up at the head of
  a non-empty event list containing only spurious events.  This
  causes an endless loop to be entered because only the sleep
  case moves the marker.

* If no events were processed and we loop the marker is now
  moved, fixing the problem.
