Log Message:
dk(4): Restore assertions in dklastclose.

We only enter dklastclose if the wedge is open (sc->sc_dk.dk_openmask
!= 0), which can happen only if dkfirstopen has succeeded, in which
case we hold a dk_rawopens reference to the parent that prevents
anyone else from closing it.  Hence sc->sc_parent->dk_rawopens > 0.

On open, sc->sc_parent->dk_rawvp is set to nonnull, and it is only
reset to null on close.  Hence if the parent is still open, as it
must be here, sc->sc_parent->dk_rawvp must be nonnull.
