URL: http://svnweb.freebsd.org/changeset/base/269353

  Fix breakage introduced by r256843: removing the SA_CCB_WAITING bit
  left some of the decisions based on its counterpart, SA_CCB_BUFFER_IO
  being random.  As a result, propagation of the residual information
  for the SPACE command was broken, so the number of filemarks
  encountered during a SPACE operation was miscalculated.  Consequently,
  systems relying on properly tracked filemark counters (like Bacula)
  fell apart.

  The change also removes a switch/case in sadone() which r256843
  degraded to a single remaining case label.
