[rr] Send a Channel Release before deactivating the channel
After auto releasing a channel the next paging request will
not be immediately answered. The hypothesis was that we do
not release the channel properly. Implementing Channel Release
of GSM 04.08 should have fixed it, but it didn't. According
to the wireshark dissectors the message is correct though.
- Add the RR cause values to gsm_04_08.
- Implement the Channel Release message
- Invoke the release channel function before deallocating
the lchan.
