caif: set traffic class for caif packets
Set traffic class for CAIF packets, based on socket
priority, CAIF protocol type, or type of message.
Traffic class mapping for different packet types:
- control: TC_PRIO_CONTROL;
- flow control: TC_PRIO_CONTROL;
- at: TC_PRIO_CONTROL;
- rfm: TC_PRIO_INTERACTIVE_BULK;
- other sockets: equals to socket's TC;
- network data: no change.
