core: skip disk profiles validation on memory disk

When we create the memory or metadata disks they are a result of live
snapshot with memory or hibernation command. In some cases the user can
own the VM, including the option to execute the above command but he may
not have the disk profile permission to add those disks.

This patch will skip the permission validation in those cases, allowing
a user that owns the VM and capable of executing the command to not fail
on the underlying addDisk command.
