io_uring: fix use-after-free by io_cleanup_req()
io_cleanup_req() should be called before req->io is freed, and so
shouldn't be after __io_free_req() -> __io_req_aux_free(). Also,
it will be ignored for in io_free_req_many(), which use
__io_req_aux_free().
Place cleanup_req() into __io_req_aux_free().
