tipc: Optimize handling excess content on incoming messages
Remove code that trimmed excess trailing info from incoming messages arriving over an Ethernet interface. TIPC now ignores the extra info while the message is being processed by the node, and only trims it off if the message is retransmitted to another node. (This latter step is done to ensure the extra info doesn't cause the sk_buff to exceed the outgoing interface's MTU limit.) The outgoing buffer is guaranteed to be linear.
