[GIT PULL] io_uring fixes for 7.0-rc1

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A few fixes did pop up for io_uring since I sent the pull request
earlier in the week, so let's flush those out for the -rc1 release. This
pull request contains:

- A fix for a missing URING_CMD128 opcode check, fixing an issue with
  the SQE mixed mode support introduced in 6.19. Merged late due to
  having multiple dependencies.

- Add sqe->cmd size checking for big SQEs, similar to what we have for
  normal sized SQEs.

- Fix a race condition in zcrx, that leads to a double free.

Please pull!
