  Eliminate deadlock potential in dahdi_fixup().
  
  (This is a backport of 269307, committed to trunk by rmudgett.)
  
  Calling dahdi_indicate() when the channel private lock is already
  held can cause a deadlock if the PRI lock is needed because
  dahdi_indicate() will also get the channel private lock.  The pri_grab()
  function assumes that the channel private lock is held once to avoid
  deadlock.
