Modify to work with phk's latest mods to cdevsw. This is a temporary

fix; it doesn't address the problem of removing the module.  If you do
the following:

  vinum stop
  fsck /dev/vinum/VOLUME

you *will* get a system crash.  What we need is a cdevsw_remove
corresponding to cdevsw_add, but that hasn't been written yet.
