libxl: remove redundant calls to virObjectEventStateQueue

In libxlDomainShutdownThread, virObjectEventStateQueue is needlessly
called in the destroy and restart labels. The cleanup label aready
queues whatever event was created based on libxl_shutdown_reason.
There is no need to handle destroy and restart differently.
