net: cxgb3: Fix an error code when probing the driver

During the process of driver probing, probe function should return < 0
for failure, otherwise kernel will treat value >= 0 as success.

Therefore, the driver should set 'err' to -ENODEV when
'adapter->registered_device_map' is NULL. Otherwise kernel will assume
that the driver has been successfully probed and will cause unexpected
errors.
