[ Upstream commit 7dbc73e6124ce4d0cfbdd6166de388e9367c47ad ]

Commit 36a50a989ee8 ("tipc: fix infinite loop when dumping link monitor
summary") intended to fix a problem with user tool looping when max
number of bearers are enabled.

Unfortunately, the wrong version of the commit was posted, so the
problem was not solved at all.

This commit adds the missing part.
