Improve the TCH/H decoder logs

- Change "6,90 kbit/s" to "5.9 kbit/s"
  A typo reported in github ptrkrysik/gr-gsm#456
- Comment out the "Error! frame_nr:" message as it turns out to confuse
  users more then it actually helps debugging.
- When voice-boundary detection is enabled write the name of decoded
  control channel messages
