[0/6] random fixes and patches for io_uring

Message

Patch 1 improves task exit cancellation. The problem is a mind
experiment, I haven't seen it anywhere, and should be rare as
it involves io_uring polling another io_uring.

Patch 2 fails netpolling with IOPOLL, as it's not supported

The rest is random cleanups.

Pavel Begunkov (6):
  io_uring: tighten task exit cancellations
  io_uring: don't allow netpolling with SETUP_IOPOLL
  io_uring: fix io_match_task must_hold
  io_uring: simplify io_uring_cmd return
  io_uring: kill REQ_F_CANCEL_SEQ
  io_uring: align iowq and task request error handling
