io_uring: make timeout sequence == 0 mean no sequence
commit 93bd25bb69f46367ba8f82c578e0c05702ceb482 upstream. Currently we make sequence == 0 be the same as sequence == 1, but that's not super useful if the intent is really to have a timeout that's just a pure timeout. If the user passes in sqe->off == 0, then don't apply any sequence logic to the request, let it purely be driven by the timeout specified.
