[SCSI] scsi_dh_alua: fix submit_stpg return
submit_stpg() will always return failure so alua_activate() will report failure via dm-multipath callback function. Even though the stpg fired successfuly dm-multipath does not know and always fails to change the valid path. By returning SCSI_DH_OK we're now skipping alua_activate()'s call to activate_complete 'fn'. But this is fine because stpg_endio() will call it via h->callback_fn().
