Although unreachable, still unregister the RCU before exiting
the thread, as documented in "qemu/rcu.h":
/*
* Important !
*
* Each thread containing read-side critical sections must be registered
* with rcu_register_thread() before calling rcu_read_lock().
* rcu_unregister_thread() should be called before the thread exits.
*/
Unregister the RCU to be on par with what is done for other
accelerators.
