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

Browse Source 
[ Upstream commit 1aff514e1d2bd47854dbbdf867970b9d463d4c57 ]

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().
