Pull io_uring fixes from Jens Axboe:

 - Fix for a regression introduced in the io-wq worker creation logic.

 - Remove the allocation cache for the msg_ring io_kiocb allocations. I
   have a suspicion that there's a bug there, and since we just fixed
   one in that area, let's just yank the use of that cache entirely.
   It's not that important, and it kills some code.

 - Treat a closed ring like task exiting in that any requests that
   trigger post that condition should just get canceled. Doesn't fix any
   real issues, outside of having tasks being able to rely on that
   guarantee.

 - Fix for a bug in the network zero-copy notification mechanism, where
   a comparison for matching tctx/ctx for notifications was buggy in
   that it didn't correctly compare with the previous notification.
