storagetm: use path to device node instead of devpath

To make the generated IDs equivalent when
- sd_device object is not provided,
- sd_device object is provided, but it does not have ID_SERIAL.

Follow-up for abc19a6ffaa94893ffc40cc000e5bb4437f67656.

This also fixes missing voidification.

Fixes CID#1524253.
