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.
