[CTS] Restart wifi before disabling always-on scanning

disabling scanning and then restarting wifi causes a race that results
in incorrect worksource being assigned to the entity that starts wifi
due to the inability to figure out when the disable always-on scanning
actually completed.

So reverse the order instead to prevent the race from happening.
