HSI: omap_ssi_core: fix possible memory leak in ssi_probe()

[ Upstream commit af0fa6f0a81585950178a468a0d1a177159c2ce3 ]

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().
