Jens Axboe 1251d2025c io_uring/sqpoll: early exit thread if task_context wasn't allocated 
Ideally we'd want to simply kill the task rather than wake it, but for
now let's just add a startup check that causes the thread to exit.
This can only happen if io_uring_alloc_task_context() fails, which
generally requires fault injection.
