  Modified files:
    sys/kern             kern_linker.c 
  Log:
  Update userref handling after discussion with submitter of previous
  patch.  lf can't be dereferenced after the unload attempt, in case it
  was freed.  Instead, decrement first and back it out if the unload failed.
  This should be relatively immune to races caused by the user since the
  userref count will be zero for the duration of the actual unloading and
  will stop further kldunload attempts.
