Subject: [PATCH net-next 03/14] tipc: move code for deleting links from bearer.c to link.c

From: Ying Xue <ying.xue@...driver.com>

We break out the code for deleting attached links in the
function bearer_disable(), and define a new function named
tipc_link_delete_list() to do this job.

This commit incurs no functional changes, but makes the code of
function bearer_disable() cleaner. It is also a preparation
for a more important change to the bearer code, in a subsequent
commit in this series.
