  Log:
      Fix bug in brelse() regarding redirtying buffers on B_ERROR.  brelse()
      improperly ignored the B_INVAL flag when acting on the B_ERROR.
      If both B_INVAL and B_ERROR are set the buffer is typically out of the
      underlying device's block range and must be destroyed.  If only B_ERROR
      is set (for a write), a write error occured and operation remains as it
      was before:  the buffer must be redirtied to avoid corrupting the
      filesystem state.
