net: net_netdev: Fix error handling in ntb_netdev_init_module()

The ntb_netdev_init_module() returns the ntb_transport_register_client()
directly without checking its return value, if
ntb_transport_register_client() failed, the NTB client device is not
unregistered.

Fix by unregister NTB client device when ntb_transport_register_client()
failed.
