But the driver should be able to veto/delay of freeing of the
softc because there may be outstanding references to it
that the driver load/unload doesn't know about.  When asked
to unload, the driver will say no.  When ready, the driver
will inidicate that it can be deleted.  the unload code (from a
clean stack) will then free the softc and unload the driver.
