aio-posix: fix build failure io_uring 2.2
The io_uring fixed "Don't truncate addr fields to 32-bit on 32-bit": https://git.kernel.dk/cgit/liburing/commit/?id=d84c29b19ed0b130000619cff40141bb1fc3615b This leads to build failure: ../util/fdmon-io_uring.c: In function ‘add_poll_remove_sqe’: ../util/fdmon-io_uring.c:182:36: error: passing argument 2 of ‘io_uring_prep_poll_remove’ makes integer from pointer without a cast [-Werror=int-conversion] 182 | io_uring_prep_poll_remove(sqe, node); | ^~~~ | | | AioHandler * In file included from /root/io/qemu/include/block/aio.h:18, from ../util/aio-posix.h:20, from ../util/fdmon-io_uring.c:49: /usr/include/liburing.h:415:17: note: expected ‘__u64’ {aka ‘long long unsigned int’} but argument is of type ‘AioHandler *’ 415 | __u64 user_data) | ~~~~~~^~~~~~~~~ cc1: all warnings being treated as errors Use LIBURING_HAVE_DATA64 to check whether the io_uring supports 64-bit variants of the get/set userdata, to convert the paramter to the right data type.
