tipc: simplify resetting and disabling of bearers
Since commit 4b475e3f2f8e4e241de101c8240f1d74d0470494
("tipc: eliminate delayed link deletion at link failover") the extra
boolean parameter "shutting_down" is not any longer needed for the
functions bearer_disable() and tipc_link_delete_list().
Furhermore, the function tipc_link_reset_links(), called from
bearer_reset() is now unnecessary. We can just as well delete
all the links, as we do in bearer_disable(), and start over with
creating new links.
This commit introduces those changes.
