This reverts commit be9fe3d8af. While I
did manage to complete multiple test runs without failures, it looks
like this change increases full test run duration by about 30 seconds
when using seven VMs. The most visible reason for that seems to be in
"breaking" active scanning quite frequently with the Probe Response
frame coming out about 40 ms (or more) after the Probe Request frame
which is long enough for the station to already have left the channel.
Since this logging change is not critical, it is simplest to revert it
for now rather than make changes to huge number of test cases to allow
more scan attempts to be performed before timing out.
