c65f5279ba io_uring: don't set REQ_F_COMPLETE_INLINE in tw 
io_req_task_complete() enqueues requests for state completion itself, no
need for REQ_F_COMPLETE_INLINE, which is only serve the purpose of not
bloating the kernel.

aeaa72c694 io_uring: never defer-complete multi-apoll 
Luckily, nnobody completes multi-apoll requests outside the polling
functions, but don't set IO_URING_F_COMPLETE_DEFER in any case as
there is nobody who is catching REQ_F_COMPLETE_INLINE, and so will leak
requests if used.

97b388d70b io_uring: handle completions in the core 
Normally request handlers complete requests themselves, if they don't
return an error. For the latter case, the core will complete it for
them.

This is unhandy for pushing opcode handlers further out, as we don't
want a bunch of inline completion code and we don't want to make the
completion path slower than it is now.

Let the core handle any completion, unless the handler explicitly
asks us not to.
