Avoid management log loop with verb >= 6

Avoid management log loop with verb >= 6

This log message is printed within check_tls(),
which is called by pre_select(), which is called
on every iteration of event loop.

When management is attached (and doesn't use own event loop),
this message sets management state to "wait write",
which arms event loop. When on the next iteration iowait
returns with "management write event is set", we call
pre_select() and print that message again, causing the loop.

Fix by simply removing this log message.
