Add cast to `unsigned int` in call to printf

The `%x` format specifier requires an argument of type `unsigned int`.
On Windows, `be32_to_cpu` is defined as `htonl`, which returns `u_long`
(aka `unsigned long`). Even though `unsigned int` and `unsigned long`
are the same size on Windows, clang will complain if `-Wformat` is
enabled.
