  Log:
  Fix memory leak of devinfo.  The leak itself was documented in
  PR/108719, but there's a simpler fix: free it after it is used, and
  then get rid of the redundant frees this causes.  Other leaks in this
  PR not yet fixed.
  
  While I'm here, remove NetBSD/OpenBSD code and some of the portability
  #defines that were getting in the way of understanding this code.  The
  devinfo bug was harder to spot because one needed to know that
  device_set_desc_copy() was used inside of one of them (one that didn't
  take an argument!).
  
  Prefer device_printf(sc->sc_dev, "...") to printf("%s:...",
  device_get_nameunit(sc->sc_dev)).  This saves almost 300 bytes.
