Method release_disk_locks

vmm/src/device_manager.rs:2612–2619

Release all advisory locks held for the disk images. This should only be called when the VM is stopped and the VMM supposed to shut down. A new VMM, either after a live migration or a state save/resume cycle, should then acquire all locks before the VM starts to run.
