  codec_dahdi: Fix output of "transcoder show" CLI command.

  In r306010 "Asterisk media architecture conversion - no more format
  bitfields", the logic for incrementing encoders and decoders when
  opening transcoder channels was changed without making the corresponding
  change when decrementing encoder / decoder channels.  The result being
  that when a channel was destroyed, codec_dahdi couldn't properly tell if
  it was an encoder or decoder, and the default case is to assume it was a
  decoder.

  This could result in negative numbers for decoders in use like in:
    VOIP6*CLI> transcoder show
    2/-2 encoders/decoders of 92 channels are in use.

  (closes issue ASTERISK-19921)
