[S390] cio: ccw_device_online_store return -EINVAL in case of missing driver

If no driver is attached to a device or the driver provides no
set_online/set_offline function, setting this device online/offline
via its sysfs online attribute will silently fail but return success.

This patch changes the behavior to return -EINVAL in those cases.
