[PATCH v2 6/6] monitor: convert monitor_cleanup() to AIO_WAIT_WHILE_UNLOCKED()
monitor_cleanup() is called from the main loop thread. Calling AIO_WAIT_WHILE(qemu_get_aio_context(), ...) from the main loop thread is equivalent to AIO_WAIT_WHILE_UNLOCKED(NULL, ...) because neither unlocks the AioContext and the latter's assertion that we're in the main loop succeeds.
