qemu: check backing chains even when cgroup is omitted
added backing file checks just before the code that removes optional
disks if they are not present. However, the backing chain code fails
in
case the disk file does not exist, which makes qemuProcessStart fail
regardless on configured startupPolicy.
Ahh, this does make sense. Thanks for the fast cleanup, on a case I hadn't tested.
