[pve-devel] [PATCH qemu-server] partially fix #3056: try to cancel backup without uuid

[Dominik Csapak]

if the 'backup' qmp call itself times out or fails, we still want to
try to cancel the backup, else it can happen that there is still
a backup running even when vzdump thinks it was canceled

qapi docs says that backup cancel always returns success, even
if no backup is running

since we hold a global and a per vm lock for the backup, this should be
ok, since we should not reach this code without that lock
