Turned out that
SelectConfiguration is only used for outgoing connections, and incoming connection from bluetooth headset using SBC codec ends up with a bitpool as large as declared by headset.
When resulting bitpool is so large that SBC frame size plus RTP header size exceeds write MTU size, number of frames per
packet becomes zero causing crash dividing by zero in
Fix this by limiting available bitpool value exposed for SBC endpoints.
