net: cpsw_new: Fix unnecessary netdev unregistration in cpsw_probe() error path

Browse source

The current error handling in cpsw_probe() has two issues:
- cpsw_unregister_ports() may be called before cpsw_register_ports() has
  been executed.

- cpsw_unregister_ports() is already invoked within cpsw_register_ports()
  in case of a register_netdev() failure, but the error path would call
  it again.
