Bug Description

* Impact
When I connect my BT headset with microphone and change profile to HFP, Pulsaudio crashes, sometimes even crashing Gnome itself.

* Test case
- Connect a bluetooth headset to the computer
- Try to change the profile to HFP from the desktop settings or the pulseaudio cli

-> the profile should get correctly selected, the service shouldn't crash

* Regression potential

The changes are in the functions handling mSBC packets which handle bluetooth HFP codecs, so any regression would concern bluetooth devices using that profile.

-------------------------------
When I connect my BT headset with microphone and change profile to HFP, Pulsaudio crashes, sometimes even crashing Gnome itself. Syslog reports:
