Pull io_uring fixes from Jens Axboe:
 "Two minor fixes in here, both heading to stable. In detail:

   - Fix error where forced async uring_cmd getsockopt returns the wrong
     value on execution, leading to it never being completed (Pavel)

   - Fix io_alloc_pbuf_ring() using a NULL check rather than IS_ERR
     (Pavel)"

  io_uring: fix error pbuf checking
  io_uring: fix lost getsockopt completions
