Pull up following revision(s) (requested by maxv in ticket #919):

        sys/net/npf/npf_handler.c: revision 1.41

Update the pointer when fast-kicking, because it may have been freed.

Before my changes the nonsensical pointer ininitialization held, but
when I started introducing sanity checks the whole thing collapsed.

Need pullup-8.
