Describe the bug

When running the RT-Thread Smart version and using an SPI TF card as a storage medium, in the SPI driver, synchronization of the send completion is implemented through the rt_completion_wait and rt_completion_done APIs. However, when running the hello example from userapps（https://github.com/RT-Thread/userapps/tree/main/apps/hello） in the ash shell, the following error occurs:

/ # hello hello world! (result != RT_EOK) assertion failed at function:rt_completion_wait_flags, line number:139


Here is the source code when the error occurs:

else { / no changes, waiting failed / result = thread->error; result = result > 0 ? -result : result; RT_ASSERT(result != RT_EOK); }


### Other additional context

When the error occurs, checking the system status， shows rt_thread_ready_priority_group = 0 and rt_scheduler_lock_nest =0. And now the status of idle thread is 0x7, the idle task is suspended. Here is the stack trace when the idle task is suspended：
