tipc: Minor optimizations to received message processing
This patch enhances TIPC's handler for incoming messages in two
ways:
- the trivial, single-use routine for processing non-sequenced
messages has been merged into the main handler
- the interface that received a message is now identified without
having to access and/or modify the associated sk_buff
