[GIT PULL] Followup io_uring fixes for 5.9-rc4

[Jens Axboe]

Hi Linus,

Two followup fixes from the pull request on Friday that were done and
tested since. I deliberated on just waiting with these until the pull
request next week, but I think we should just get them in now. One is
fixing a regression from this merge window, the other are a followup
cancelation fix. Both have gone through full testing, and both spawned a
few new regression test additions to liburing.

- Don't play games with const, properly store the output iovec and
  assign it as needed.

- Deferred request cancelation fix (Pavel)

Please pull!
