Avoid multiple client sockets in pingpong bluetooth example
This commit guards against creating multiple client sockets if multiple
services are found. In addition the service scanning is stopped when
a service has been found and we start connecting a bluetooth socket.
Fixes: QTBUG-100289
Pick-to: 5.15 6.2 6.3
