io_uring: fix personality idr leak
We somehow never free the idr, even though we init it for every ctx. Free it when the rest of the ring data is freed. Fixes: 071698e13ac6 ("io_uring: allow registering credentials") Reviewed-by: Stefano Garzarella <sgarzare@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
