Make `t_phone::mutex_3way` recursive to avoid a deadlock
`t_phone::mutex_3way` can be locked twice when hanging up a conference
call:
- `t_phone::cleanup_3way_state()` acquires a lock
- `t_audio_session::stop_3way()` is called
- `t_audio_session::get_peer_3way()` is called
- `t_phone::get_3way_peer_line()` is called
- which acquires another lock
Making that mutex recursive is a simple way to work around this issue.
