net: mana: Don't overwrite port probe error with add_adev result

In mana_probe(), if mana_probe_port() fails for any port, the error
is stored in 'err' and the loop breaks. However, the subsequent
unconditional 'err = add_adev(gd, "eth")' overwrites this error.
If add_adev() succeeds, mana_probe() returns success despite ports
being left in a partially initialized state (ac->ports[i] == NULL).

Only call add_adev() when there is no prior error, so the probe
correctly fails and triggers mana_remove() cleanup.
