firmware: stratix10-svc: fix error handle while alloc/add device failed
If add device "stratix10-rsu" failed in stratix10_svc_drv_probe(), the 'svc_fifo' and 'genpool' need be freed in the error path. If allocate or add device "intel-fcs" failed in stratix10_svc_drv_probe(), the device "stratix10-rsu" need be unregistered in the error path.
