HSI: omap_ssi_core: fix possible memory leak in ssi_probe()
If ssi_add_controller() returns error, it should call hsi_put_controller() to give up the reference that was set in hsi_alloc_controller(), so that it can call hsi_controller_release() to free controller and ports that allocated in hsi_alloc_controller().
