rG31069fdbdae1: kevent: do not check knote lists being empty before removing a knote

Summary

If knote belongs to the list, there is no reason to check for the list
emptiness.  On the other hand, if the knote does not belong to the list,
then checking for emptiness is not enough since there might be a
different knote there.
