Jens Axboe c8b5e2600a io_uring: use type appropriate io_kiocb handler for double poll 
io_poll_double_wake() is called for both request types - both pure poll
requests, and internal polls. This means that we should be using the
right handler based on the request type. Use the one that the original
caller already assigned for the waitqueue handling, that will always
match the correct type.
