vm: enabling memory snapshot without disks

Taking a memory snapshot of a VM without disks should be
supported (or merely with Cinder/LUN disks for that matter).

Hence, removing the early return on 'VM -> snapshot'
in case 'newDrives' is empty.

Instead, proper logging will be added on consecutive patches.

Possible configurations and settings that lead to this flow:
* Unchecking all the disks in the create snapshot dialog.
* VM with only cinder disks.
* VM without disks.
