libxl: don't set hasManagedSave when performing save
    
    libxlDoDomainSave() is used in both the save and managedsave code
    paths but was unconditionally setting hasManagedSave to true on
    success. As a result, undefine would fail after a non-managed
    save/restore operation. E.g.
    
    virsh define; virsh start
    virsh save; virsh restore
    virsh shutdown
    virsh undefine
    error: Refusing to undefine while domain managed save image exists
    
    Modify libxlDoDomainSave() to take an additional parameter to
    specify managed vs non-managed save, and change callers to use it.
