[GIT PULL] io_uring fixes for 6.0-rc4

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Two parts in this pull request:

- Single fix for over-eager retries for networking (Pavel)

- Revert of the notification slot support for zerocopy sends. Turns out
  that even after more than a year or development and testing, there's
  not full agreement on whether just using plain ordered notifications
  is Good Enough to avoid the complexity of using the notifications
  slots. Because of that, we decided that it's best left to a future
  final decision. We can always bring back this feature, but we can't
  really change it or remove it once we've released 6.0 with it enabled.
  The reverts leave the usual CQE notifications as the primary interface
  for knowing when data was sent, and when it was acked. (Pavel)

Please pull!
