[GIT PULL] io_uring fixes for 7.2-rc1

Hi Linus,

A few io_uring fixes that came in during the merge window. This contains:

- Fix a file reference leak in the nop opcode when used with
  IOSQE_FIXED_FILE.

- Preserve the SQ array entries when resizing the ring via the register
  path.

- Preserve the partial result for an iopoll request rather than
  overwriting it.

- Don't audit log IORING_OP_RECV_ZC.

- Bound io_pin_pages() by the page array byte size in the memmap path.

- Follow-up cleanup to the task_work mpscq conversion, getting rid of
  the now-unnecessary tw_pending tracking for the !DEFER_TASKRUN path.

- Switch a system_unbound_wq user over to system_dfl_wq

Please pull!
