Subject: [PATCH net-next 05/16] tipc: Don't record failed publication attempt as a success

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

No longer increments counter of number of publications by a node
if an attempt to add a new publication fails. This prevents TIPC from
incorrectly blocking future publications because the configured maximum
number of publications has been reached.
