Subject: [PATCH net-next 07/20] tipc: Eliminate message header routines for caching destination node

From: Allan Stephens <allan.stephens@...driver.com>

Gets rid of a pair of routines that provide support for temporarily
caching the destination node for a message in the associated message
buffer's application handle, since this capability is no longer used.
