io_uring: optimise io_req_task_work_add()
Inline io_task_work_add() into io_req_task_work_add(). They both work with a request, so keeping them separate doesn't make things much more clear, but merging allows optimise it. Apart from small wins like not reading req->ctx or not calculating @notify in the hot path, i.e. with tctx->task_state set, it avoids doing wake_up_process() for every single add, but only after actually done task_work_add().
