core: fix upgrade of vm_devices for 3.1

on patch Ic83725ad the execution of script 03_01_0440 was commented out,
because it was mistakenly assumed it is not needed, since 03_01_0560
handle vm_device upgrade.

this was wrong since 03_01_0440 handles a FK violation,
so uncommenting it to be executed on upgrade.
