libxl: Fix libvirtd crash on domain restore

Commit cc2a3c2a94 missed one case in the libxl driver where virDomainDef
is returned from libxlDomainSaveImageOpen and a g_steal_pointer is needed.
Without it, the virDomainDef object is freed and the driver crashes later
in the restore process when accessing the object.
