Subject: [PATCH net-next] net: dsa: loop: Print when registration is successful

We have a number of error conditions that can lead to the driver not
probing successfully, move the print when we are sure
dsa_register_switch() has suceeded. This avoids repeated prints in case
of probe deferral for instance.
