  SVN rev 188484 on 2009-02-11 14:25:09Z by jhb
  
  Fix lptopen() and lptclose() to not trash the state of the HAVEBUS flag
  in 'sc_state'.  This allows the lpt_release_ppbus() calls in those two
  routines to actually release the ppbus and thus fixes the hangs noticed
  with the lpt(4) driver since the recent ppbus changes.  The old lpt(4)
  driver didn't actually check the HAVEBUS flag in lpt_release_ppbus() which
  is why these bugs weren't noticed before.
